(Whiteboard: [platform-rel-Intel]) 

I'm on a Lenovo ThinkPad X201 with this graphics card as reported by about:support:

Adapter Description: Intel(R) HD Graphics
Vendor ID: 8086
Device ID: 0046

The graphics performance is poor. Opening new tabs, for example, is very chunky. Setting gfx.direct2d.disabled to true in about:config makes the browser much smoother.

Should we blacklist this card for Direct2D?
How is IE9 for you?
Huh, that's weird. Installing IE9 fixed the speed issue in Firefox! The FishIE tank demo on beta8 beats IE in framerate now.
Hmm, that's not entirely true: the animation when opening new tabs is still much slower with Direct2D on than with it off. So it seems to be a tradeoff now.

Not too weird :) IE9 installs some MS hotfixes for D2D and DirectWrite.

It's interesting that this specifically is slow, I wonder what makes it slow, is this animation slow with Direct2D -off- (graphics.direct2d.disabled true) but leaving accelerated on?

To be fair, somewhat of a tradeoff is expected, some operations are just fundamentally slower with hardware acceleration but that should be a minority. And we should ensure it does not adversely effect the UI experience.
Sorry, the above comment was meant for different bug.
Also bug 692736 and bug 688050 have the same card ID as this one.
What card is it and why it it that slow?
I have Dell Inspiron 17R with Intel HD Graphic
Adapter Description: Intel(R) HD Graphics
Vendor ID: 8086
Device ID: 0046
Graphics performance is poor.
I still don't know what is the model number of this card.
See https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers, where the GPU family is something like "900" or "X3000". Couldn't find anything via Google either, maybe this is one of the very first Intel GPUs?
Device ID%: PCI\VEN_8086&DEV_0046&SUBSYS_04571028&REV_12

Intel® GME/GLE 965
Current Driver Installed 8.15.10.1749 
Driver is current
Ok, do you have Firefox 7? Then please post Graphics section from about:support.
From the "blocklist" link:
"Up to and including Firefox 6, on certain GPUs in the GMA X3000 generation (G35, GL960, GM965), we block Direct2D. See bug 595364. In Firefox 7 and newer, Direct2D is no longer blacklisted on these GPUs. "

So, I think your GLE965 would be in the X3000 family and thus it needs at least driver version 8.15.10.1930. It should exist, try searching harder.
E.g. I found this link that I think could be for your laptop. There is no 17R model, but according to google it is called N7010:
http://support.dell.com/support/downloads/driverslist.aspx?os=W764&catid=6&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=INSPIRON_N7010&hidos=W764&hidlang=en&TabIndex=&scanSupported=False&scanConsent=False

They offer 8.15.10.2104.
Currently Firefox 10.0a1, but problem is same.

Did you force direct2D enabled in about:config? Or is it used automatically by Firefox?
Yes, Dell N7010
Just set gfx.direct2d.force-enabled = true
Same problem.
Also same defect on Intel® G41. (Intel E6700)
Do not set it to true. I asked if you set force-enabled to false, if Firefox still enables Direct 2D.

Can you also post about:support (Graphics) from the G41 machine?

OK, so counting this bug and bug 692736 there are 3 people claiming Direct2D is making UI slower than when it is off, on the 0046 card ID. However, test in bug 692736 comment 6 shows that page content is faster with Direct2D. So it seems to be a tradeoff. Not a clear case for blocklisting.

Do you have Internet Explorer 9 installed? I read in another bug that it installs some Direct2D patches that increase performance. Would it be possible for you to install it?
Yes, IE 9 installed. Windows 7.
I think that the problem is not in the browser, but rather in the drivers.
Recently tried WebGL in Google Maps - bad result as Firefox and in Chromium.
But WebGL is quite different from Direct2D.
Sorry, did not know
Test with http://demos.hacks.mozilla.org/openweb/HWACCEL/

4 FPS (all defaults, HWA disabled):
   FireFox UI is fast, Panorama is slow
15 FPS  ( layers.prefer-d3d9=True, HWA enabled):
   UI and Panorama is reactive, font is ugly
60+ FPS (all defaults, HWA enabled):
   firefox interface and Panorama is terribly slow 

Strange results...
(In reply to aceman from comment #27)
> But WebGL is quite different from Direct2D.

Yes and no. WebGL goes through ANGLE on Intel chipsets, meaning that ultimately WebGL performance is tied to DirectX performance.

Using D3D9 disables Direct2D (and DirectWrite font rendering), so the middle results aren't overly surprising.

It actually might very well even cause reasback, you want to layers.direct2d.disabled=true, that will fallback to D3D9 and disable D2D.
Is there a way to disable Direct2D only for FF interface (chrome)?
That would be what this bug requests, because accelerating page content seems to work and give positive results.

The second part is:
If we find out the acceptable settings, would it be possible to make them FF default for this range of cards?
At least add graphics to blocklist, because many people use laptops with integrated video and move from Firefox to Google Chome through a slow interface.
Yes, that would be the last resort solution, if no better settings can be found. Because as you could benchmark, leaving Direct2D enabled does have some advantages (at least for content).

Have you tried IE9? Does its UI work fast?
Having similar issues with firefox and HD Graphics, I can assure you, that firefox is waaaay slower than IE and Chrome in terms of UI rendering. IE, opera and chrome are fast and smooth.

OK, what is the result with gfx.direct2d.disabled but Direct3D 10 enabled (check the state in about:support)?
44 FPS ( gfx.direct2d.disabled=0, HWA enabled): 
firefox interface and Panorama is terribly slow.

You must set gfx.direct2d.disabled to true not 0. As you can see in your about:support  in comment 38, your Direct2D is still enabled. Please retest.

What is the difference in comment 40 and comment 39? Both IE 9 but different FPS? Why is that?
Comment #40 is misprint.
15 FPS ( gfx.direct2d.disabled=true, HWA enabled): 
UI is fast and smooth.

There is Direct3D 9 again. I wanted 10. But maybe Direct2D and Direct3D 10 are connected and you can't get one without the other.
Yes, when set gfx.direct2d.disabled=false:
    GPU Accelerated Windows1/1 Direct3D 10
but when gfx.direct2d.disabled=true:
    GPU Accelerated Windows1/1 Direct3D 9
Today install Firefox 11. The problem with smooth animation in the new version left.
This is evident not only in the pages of active motion,
but on the interface for programs to open and close tabs.

        direct2d
Seems like this issue hits nhl.com very hard it is unusable with direct2d enable on my machines with Intel graphics.

Over a year and nothing going...guess I'll be leaving d2d disabled for a while...
Just tried to explore the site with Firefox 14 and hardware acceleration, the laptop was warm, cpu high usage, and the interface site was lagging.
Very sad that Chrome everything works fine with acceleration. 
Maybe problem not in drivers.
Are you sure Chrome uses acceleration there?
Chrome doesn't accelerate content drawing at this point in release versions. Nor does it use Direct2D. It just accelerates composition, like the direct3D 9 support you're seeing when Direct2D is disabled. Could you confirm disabling Direct2D through your about:config, but leaving Direct3D9 enabled resolves your issues?
Drivers latest.

Firefox
http://demos.hacks.mozilla.org/openweb/HWACCEL/ only 45 FPS
nhl.com - lag/
Chrome
about:flags 
GPU compositing on all pages - On
http://demos.hacks.mozilla.org/openweb/HWACCEL/ only 15 FPS
nhl.com works fine
What params change in about:config?
On the bottom of about:support, you see Direct2D (having true or false as value) and "GPU accelerated windows" (having Direct3D 9 or 10 as value).
I don't know much about this stuff (for example how to leave d3d enabled, is that by leaving hardware acceleration option on?) but here is what I see:

Hardware on and direct2d in config on: lag
Hardware on and direct2d config off: no lag
Hardware acceleration off: no lag

With hardware accel. on and d2d disabled in about:config I see that d2d is indeed disabled and GPU Accelerated Windows1 is Direct3D 9 in about:support.
Windows 7 64bit
Current settings with lag:

Direct2D Enabled true
DirectWrite Enabled true (6.1.7601.17776)
GPU Accelerated Windows1/1 Direct3D 10
AzureBackend direct2d
I think HW acceleration in Options->Advanced->General turns both Direct2D and Direct3D off.
You must leave that option on, but in about:config filter for Direct2D and set the found options so that it is disabled (I can't spell them currently as I am on Linux).

It seems alldred got it right.

This sounds like you did the right thing, and does indeed suggest that Direct2D is responsible for the issues you're seeing and not hardware acceleration performance in general. Considering your WebGL result it seems to be caused by poor GPU performance in general for things more advanced than simple compositing. The reason is a little hard to say still, could you check if power saving mode affects it? Additionally it would be helpful if you could specify the exact notebook type/hardware so we can try and acquire hardware that can reproduce the issues.

Interesting: Is Firefox on Linux works fine on Intel HD?
I ready to change my system for such)))
Is WebGL that test Andrew linked?

I get 60+ fps with direct2d on, 18 fps with direct2d off/direct3d on, and 10fps with all hardware acceleration off.

I'm using an inspiron e6410 with Intel HD graphics on the i5-540m cpu.

I think you might be able to check this out on any system with Intel HD/HD2000/HD3000 graphics though.  My HTPC has an i5-2300 (HD2000 graphics) and the issue is exactly the same with the fps test in those same 3 conditions giving 60+/25/12.
Oops i mean Dell Latitude e6410 not inspiron.
Andrew, HW acceleration in Firefox on Linux does nothing, so yeah, it works fine :)
Apparently nhl.com performance has been discussed already here: https://bugzilla.mozilla.org/show_bug.cgi?id=690623

Not sure how that gradient thing ties into the direct2d.
I get 60+ fps with direct2d on = 29fps
with direct2d off/direct3d on = 14fps
with all hardware acceleration off = 6fps
but my screen size 17" (1600x900)

> Andrew, HW acceleration in Firefox on Linux does nothing, so yeah, it works

what Linux distributive you use?
That is not important because universally there is not much acceleration on linux.
Only WebGL is accelerated on the graphics card (OpenGL).
There is no equivalent to Direct2D. (Maybe just XRender that is internal to the X server.)
There is equivalent to "GPU accelerated windows (Direct3D)" via OpenGL but it is not yet enabled as it is very buggy.
So there you go :)
this site http://inception-explained.com/  gives about (I assume) 4-5 fps while scrolling on my win 8 CP x3100     nightly ux 14 (with forced d3d HA true)
this site http://inception-explained.com/ lagging in ALL browsers on my DELL Inspiron N7010.
I am experiencing the same issue, Firefox's is very sluggish and there is a almost permanent latency between user input and firefox response. My system is a DELL XPS L502X with intel hd-3000 and nvidia Geforce GT 540M in a nvidia optimus configuration.

The only way to resolve the issue was to set Firefox to use the Nvidia card instead of intel hd-3000 (this is the default setting) from nvidia's control panel.

The processor Power-state is referenced here, but there also the "Intel Graphics Power Plan" under the Intel Graphics settings in the windows power options configuration. It may help to set the "Intel Graphics Power Plan" to "Maximum Performance", it may reduce the latency that exists between user input and Firefox's response because the graphics card will be already (i hope) in high performance mode.

We need more in debt profiles. The theory here would be that CPU usage during the slow response is low, and GPU usage is high. If that's not correct we need to examine things more closely.

Can you be more specific, any guide how to do it?
Gmail is dreadfully slow for me with hardware acceleration enabled on Windows 8. Would this be the appropriate place to post my information as well, or would I be better served by filing a new bug?

The animations during going in and out of Customization in Fx29 are slideshow-slow.

Also website-animations like the accordion on www.mozilla.org are really slow too.

Yet, in IE11, the same website-animation is blazing fast by comparison.

There's no problem with the GPU, but how it's used.
I'm using Firefox 29 on Ubuntu 14.04 (running on an old core i5 with Intel HD 4000 graphics), and it's not bad. When I go to www.mozilla.org, everything is awesomely smooth and responsive. With Gmail the inbox still janks every now and then (every couple of seconds or so). Many other pages do not scroll smoothly at all, like this one: http://www.zdnet.com/torvalds-clarifies-linuxs-windows-8-secure-boot-position-7000011918/

If I open up something like Jenkins in the office with autoscroll enabled (we have a very long list of Jenkins items) and I scroll slowly, it's smooth most of the time, but it still janks every couple of seconds (thereabouts). It "feels" like there is some kind of garbage collection going on that freezes the UI for a split second, or that all operations required to render the page 60 times per second sometimes take longer than 16.6ms to complete (hence the jank). The same behaviour occurs on most lengthy pages (where you can vertically scroll long enough to see it), and especially on pages when with embedded videos and images (when scrolling vertically, janking always occurs when you have to scroll past an embedded YouTube video). Same thing occurs for pages like Twitter and Google+. I understand that pages with infinite scroll lists will pause when they have to perform a network operation to load more of the page, but even when you scroll back up, it's not consistently smooth (judders/janks/stutters occur).

While this may be considered a small imperfection (which I agree it is) it's still annoying as it prevents the end-user experience from being flawless. As is well known by Apple and fairly recently discovered by Intel (after reverse engineering the iOS user experience), they key to success in today's market is a smooth and responsive UI. That is, a consistently smooth 60 frames per second, and low latency (no more than 15ms).
Firefox 33.0.2 on Intel HD3000 just is slow.
Confirmed on stable Firefox 36 on Intel HD3000 (Windows 7)
I have a samsung ultra 7 laptop with an intel HD4000 integrated graphics and an AMD radeon HD 8700M. For some reason firefox is locked to using the "power saving" option and cannot be set to use the radeon "high performance" option. this means i have to use another browser for flash or html5 video!
almost every single other application has the choice in the catalyst control panel as to which graphics card it runs in, but fro some reason firefox has a lock icon and will only run on the intel card.

Use that while focusing on workloads that are specifically slow.
