1089297 - High CPU or GPU usage with Thumbnail Zoom Plus & OMTC (offmainthreadcomposition) on Windows

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[David Adler]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141023194920

Steps to reproduce:

I'm the developer of the Thumbnail Zoom Plus add-on, reporting this problem which several of my users have seen; I haven't seen it myself.

When layers.offmainthreadcomposition.enabled is true (default in Firefox 33), some users see high CPU usage, high GPU usage, fans running loudly, or a high-pitched whine (which can mean high GPU usage).   It starts when an image pop-up is shown from Thumbnail Zoom Plus, and stops when the pop-up is dismissed.  This happens fairly consistently, at least 90% of the time, on affected systems.

The problem does NOT happen if users set layers.offmainthreadcomposition.enabled to false in about:config.

To reproduce on an affected system:
1. Installed Thumbnail Zoom Plus https://addons.mozilla.org/en-US/firefox/addon/thumbnail-zoom-plus/
2. Visit an image-heavy site, such as http://www.reddit.com/r/pics/
3. Hover the mouse over thumbnails or links to get image pop-ups.  Listen for fan running.  Monitor CPU temp and CPU usage %.  Watch for high usage.

Environment (user 1): Windows 7 x64, i5 2.6GHz AMD 7850
Environment (user 2): Windows 8.1.  7970 GPU with recent Catalyst build.
Firefox versions: 33.0, Nightly 36.0a1 (2014-10-19)
Thumbnail Zoom Plus version: various, including 3.1 .  



Actual results:

Worked, but caused fan to run fast or hardware to "whine" (which may be excessive GPU use).   One user reports his CPU temp rose from 53 to over 65 deg C.


Expected results:

Not use excessive CPU or GPU cycles.

[David Adler]

As a workaround I've been telling users to set layers.offmainthreadcomposition.enabled to false, which works.  But I don't know if that workaround will always be available, and not everyone knows to do that.

Comment 2

[David Adler]

Thumbnail Zoom Plus displays its pop-up in an XUL window which contains an <html:img> inside an <html:div> inside an xul <vbox> and other elements.

For add-on source, download the add-on or see the repo at https://github.com/dadler/thumbnail-zoom/releases/tag/v3.1

Could you ask to one of your users hitting this issue to join BMO, please, it would help to speak directly with him.
In addition, could you ask them the "graphics" section from about:support.

Comment 4

[David Adler]

I've emailed four users who reported the problem and asked them to comment here with the "Graphics" section.

When I first informed David of the issue I was running a 7850, am now running a gtx970. I've also downgraded back to ff 32 till this is fixed.

The "coil whine" is the noise my gpu makes when it renders at 600fps+

I also experienced coil whine until disabling layers.offmainthreadcomposition with an i5/GTX 760/Win7x64/FF33.

Hello. Same for me here. Disabling aforementioned option solved the problem.
The browser is Aurora 35.0a2. Here's the log from the laptop:

------------------------

The situation is the same for my PC. I have same graphics as [e-mail] (GTX 760 w/2GB RAM). I can paste the config when I have access to that PC if you want. :)

What's more important, is that it seems that this option (layers(...)) is disabled on Linux Firefox by default (same hardware as I've pasted above) and there's absolutely no problem with David's extension.

Milan, these are 3 different graphics cards... not sure if this is known or related to existing issues? :-)

Comment 11

[David Adler]

I user sent a great clue, so now I know how to reproduce the problem!

Basically it happens only when the Thumbnail Zoom Plus pop-up appears under the Windows Task Bar in task-bar-always-on-top-mode.

To reproduce:

1. On a Windows machine, launch Firefox 33.0.1

2. Install Thumbnail Zoom Plus (TZP) 3.1 and disable all other add-ons.

3. Make sure layers.offmainthreadcomposition.enabled is true.

4. Restart firefox.

5. In Thumbnail Zoom Plus settings, make sure "Max Size" is set to "Window".

5. Go to any page from which you can cause TZP to display a pop-up; I suggest http://www.reddit.com/r/aww/comments/2l00kf/what_happens_you_mix_a_husky_and_a_golden/

6. Resize the Firefox window to be fairly short; we want it to be shorter than the pop-up's image.  Position the Firefox window so its bottom is below the bottom of the screen.

7. Drag the Windows task bar to the bottom of the screen.

8. Right-click the task bar, go to Properties, and turn on Keep the taskbar on top of other windows, and turn off Auto-hide.

9. Start Windows Task Manager and position it so you can see it and Firefox simultaneously.

10. Click in the Firefox window (so it has focus) and then hover the icon or link in the reddit page.  A Thumbnail Zoom Plus pop-up should appear.  The bottom of the pop-up should be below the bottom of the screen; if it isn't, reposition the Firefox window lower and hover again.  See attached screen shot https://bug1089297.bugzilla.mozilla.org/attachment.cgi?id=8515564 .

11. Notice that Task Manager shows Firefox continually busy while the pop-up is displayed, even if you don't move the mouse or do anything else for a long time.  On my system it stayed 48-66% busy.  Note: Since Windows considers my machine to have two cores, I suspect 50% means a single processor (one thread) is 100% busy.  On a machine with more cores I suspect one thread busy might appear as a lower %.  In any case, this is a sign of the problem: Firefox should use very little CPU while the pop-up is being displayed but nothing is happening.

The problem doesn't happen if any of these are the case:
* layers.offmainthreadcomposition.enabled is false
* the pop-up isn't covered by the task bar
* the task bar's always-on-top is mode is off.

My environment:
Windows XP Home SP3
Single-core machine with hyper-threading, so appearing as a two-core machine.

Attachment: Profile.json

I used Firefox Developer Tools to capture a profile while the problem was happening.  I profiled with the pop-up displayed but nothing else happening for at least half a minute.  It shows:

100% root
100% Startup:XRE_Main
76% IPDL:PCompositor::SendFlushRendering

The full profile is attached to this bug report as Profile.json .

Comment 13

[David Adler]

One user reported that the problem also happens with the Firefox maximized, but that may depend on the Windows version.  In  XP, maximized didn't cause the problem, but non-maximized and under task bar did.

Comment 14

[David Adler]

Ping... I've posted steps which I think can reproduce the problem on any Windows machine.  Is there anything else I can do to help?  Is anyone from Mozilla able to investigate?  Thanks,
David

[Milan Sreckovic [:milan] (needinfo for best results)]

33 had its share of critical problems on Windows, we didn't get to this yet.

Comment 16

[Jee]

I just realized what was making the noise and found this thread.
I was browsing reddit and I can reproduce it everytime while looking at this thread:
(http://www.reddit.com/r/eu4/comments/2nhl67/what_should_be_my_next_move/)

If I put my mouse over the thread's title, my cpu isn't skyrocketing, neither if I expand the image.
It only happens while hovering the thumbnails IF firefox is maximized. Cpu also stay calm if firefox isn't maximized, or in fullscreen mode (f11).

Disabling or removing all other addons didn't matter. As David Adler said, changing the "max size" to something else than "window" also seems to fix the problem.

Please tell me if I can do more testing, I got way too much time this month :].

Nevermind what I just said about the thread's title/expanding the image (through reddit enhancement suite). While looking at this other thread:
http://www.reddit.com/r/techsupportmacgyver/comments/2nhitl/led_sign_only_has_female_rs232_for_programming_no/
the cpu is maxed no matter where/what I hover. Food for thought: it seems to be related to the image being bigger than the space available. No idea why it doesn't trigger when over the first Thread's title though, but it *seems* to only happens on image what are bigger than my screen resolution (1360x768)

[David Adler]

As original submitter, I think this bug can be closed since Thumbnail Zoom Plus is no longer available for Firefox and since it's been 6 years without issue activity.
