Steps to reproduce:
Upgraded to firefox 88.0
Actual results:
All tabs are blank. Tab bar and URL bar are updated intermittently, if at all. Hamburger menu is missing text for some entries.
The window title does appear to be updated, and by typing blindly into the URL bar I can make the title update, so I think it's a rendering problem.

More info:
If I try to open the devtools with ctrl-shift-I, nothing happens at first, but if I switch to another window and back, the devtools appear.

The Bugbug bot thinks this bug should belong to the 'Firefox::Address Bar' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Moving back to general because it looks like a more general issue.
I'd suggest to check your graphic drivers for new versions.
As a second suggestion you could try to force disable webrender, if it got enabled, using gfx.webrender.force-disabled = true in about:config (or just disable it if you enabled it manually) and checking if that helps.
This may also help: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Thanks. Can confirm that running in safe mode fixes the problem, as does disabling webrender.
As for updating the graphic drivers: I'm using the latest packages in Ubuntu 20.04. I'd prefer not to have to start installing binary packages from elsewhere, but could do if it would help diagnose the issue.
I should mention for context that this seems similar to some problems I had with applications based on Electron 11 (https://github.com/electron/electron/issues/27889).

Hey Richard,
If running Safe mode fixes the problem you might want to try a fresh new profile could help. You can find more about creating a new profile here : https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile .
If possible, you can test this issue on the nightly build as well. Download the build from : https://www.mozilla.org/en-US/firefox/nightly/all/ .
Let us know if any of these works as well.

Thanks. No improvement with a new profile or with the latest nightly.

Setting a component for this issue in order to get the dev team involved.
If you feel it's an incorrect one please feel free to change it to a more appropriate one.

Hi Richard, could you please go to about:support, click on "Copy text to clipboard", and attach the copied text to this bug. If you could do that both with webrender enabled (buggy) and webrender force-disabled (working correctly) that would be really helpful. Thanks!
Additionally, if you would be able to use mozregression to determine what caused the bug that would be incredibly helpful! On linux it's easiest to install and run on the command line:
pip install mozregression
mozregression --good 87
This will download and run a series of versions of firefox. For each one, you answer "good" or "bad", and eventually it will tell you what change introduced the bug. If you need any help with that please let me know.

Hi Jamie,
I had to expand the search space: I guess I should have tested with other versions before. Sorry if my implication that the problem was introduced in 88.0 led to any wasted time.
mozregression
reports:

... which I guess is consistent with the fact that disabling webrender fixes the problem for me!

Thanks for that richard. Would you be able to try running mozregression from even further back (eg an older "good" version), and this time add --pref 'gfx.webrender.all:true'
to the command line?

I wasn't able to find a "good" version with that setting enabled. v67.0 exhibits the same behaviour as I reported above. Earlier versions seem to segfault on startup.

I am also seeing this in two situations:
-
On a Debian buster laptop running mate, with Intel HD Graphics 620 on a Core i7-7600U. This happens immediately when Firefox is launched. I previously had disabled WebRender, but as of Firefox 92, perhaps it got re-enabled as it is now doing it on launch again. I am upgrading the laptop to bullseye to see if it resolves.
-
On a Debian laptop (this problem existed with both buster and bullseye), things are fine initially, but start to exhibit this same behavior after a disconnecting or reconnecting an external display. That laptop has Intel CoffeeLake-H GT2 [UHD Graphics 630] and a Core i7-9750H. I reported that bug in #1730611.
The symptoms in both cases are identical to the ones reported here: the title bar changes, but the UI is generally nonresponsive or only marginally responsive.

Update to case 1 - the laptop where it manifested the issue at startup:
Upgrading to Debian bullseye did not address the problem.
Searching turned up discussion on https://www.reddit.com/r/firefox/comments/pkronz/ff92_disable_webrender_once_and_for_all_come_rain/ and https://www.reddit.com/r/firefox/comments/pkfjsn/petition_to_keep_gfxwebrenderforcelegacylayers_in/
Setting gfx.webrender.software to true worked around the issue. I had to run Firefox in safe mode to be able to get to about:config (note - no extensions are in use here).

I don't think the xfce tag is accurate here.
Of the two laptops I described, the first is running Mate, and the second is running xfce. The Mate one is the one experiencing the issue most directly applicable to this bug.

Found this:
https://gitlab.xfce.org/xfce/xfwm4/-/issues/578
Currently running XFCE 4.16, on debian 11.
When enabling the compositor in settings, Firefox v91 becomes completely unusable. You have to wiggle the window around so the url box updates. Pages don't load at all, unless you restart the browser. Then, it'll load partially. When running firefox in console, no errors are outputted at all.
https://files.catbox.moe/8cggd1.mp4
Enabling/disabling compositing on the fly is not necessarily well handled by applications, this is not something I would recommend.
https://gitlab.xfce.org/xfce/xfwm4/-/issues/540
It would seem that Xfce's compositor, when used with Xorg TearFree, makes Firefox's UI stop rendering.
It's the use of “present” for vblank that breaks it. But thing is, xfwm4 is not responsible for the client redering itself, so this bug is between the driver and the client, not a bug in xfwm4.
The reason it affects xfwm4 on intel is because xfwm4 automatically selects present for vblank on intel hardware.
Closing, this is not a bug in the compositor.

Following https://gitlab.xfce.org/xfce/xfwm4/-/issues/540, it sounds like this might be a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1705148? I don't have the TearFree option enabled, but from https://gitlab.xfce.org/xfce/xfwm4/-/issues/540, it sound like that might not be that relevant?

What does $ xrandr --listproviders
say? Does it end with "intel" or "modesetting"?

As for updating the graphic drivers: I'm using the latest packages in Ubuntu 20.04.
You would neeed to switch to the modern modesetting driver.

The use of this driver is discouraged if your hw is new enough (ca. 2007 and newer). You can try uninstalling this driver and let the server use it's builtin modesetting driver instead.
Can this bug be fixed with $ sudo apt remove xserver-xorg-video-intel
and a reboot?

Another duplicate then - it's really time to blocklist the SNA driver for HW-WR.

Comment 23•3 years ago

The Intel DDX driver is known to cause troubles with HW-WR and
has been deprecated by most distributions, in favor of the glamor
based "modesetting" driver.
Lets blocklist it. This will mostly affect older/legacy setups.
Note: the xrandr boilerplate code in glxtest will be useful for
better multi-screen detection in a follow up patch. The current
legacy X11 screen detection does not work in composited environments,
always reporting one single big screen with the combined size.
Xrandr allows for correct detection in such setups.

I can confirm the laptop in question had been configured some time back to force it to use the Intel driver, for an unrelated reason. I removed that restriction and this problem went away.

Looks like we should backport this one to ESR and beta as well - will request that after a couple of days.

Memo to myself: the patch here will only work on xrandr >= 1.4, however we require only 1.3 (indirectly through GTK). So there are systems where the check would early-out. OTOH xrandr 1.4 was released in early 2013, so such setups are unlikely to get HW-WR anyways.

regression range:
... --good 2016-02-01 --bad 2017-02-01
This is software archaeology!
Should be bug 1197954 - in other words, the Intel DDX driver does not work with the GLX Vsync source.

Bug 1710400 - Blocklist HW-WR on Intel DDX driver, r=aosmond
Beta/Release Uplift Approval Request
- User impact if declined: Some Intel users using an older Xorg driver will have issues raging from glitches to stalls.
- Is this code covered by automated tests?: Yes
- Has the fix been verified in Nightly?: Yes
- Needs manual test from QE?: No
- If yes, steps to reproduce:
- List of other uplifts needed: None
- Risk to taking this patch: Low
- Why is the change risky/not risky? (and alternatives if risky): Blocklist change / change in
glxtest

Bug 1710400 - Blocklist HW-WR on Intel DDX driver, r=aosmond
The regression dates back to Firefox 50, the patch landed in nightly a day ago and the affected population is probably very small. I Don't think this is a good candidate for an uplift in our final beta before building our release candidate. Let's have that patch ship with 94 and get some bake time in pre-release channels . I am leaving the esr uplift request open for next cycle, thanks.

This regression range is actually not correct, at least not for default configurations. The first version were we shipped hardware Webrender (and thus any hardware acceleration) on Linux was 84 (bug 1675766), but a large group of the affected users (of this bug) only got it in 89 (bug 1702301). So ESR 91 is certainly the first ESR which is affected.

Given the amount of duplicate bugs, I'm afraid the number is not super small (for Linux). But we can certainly let it ride the trains.

This is software archaeology!
I love mozregression and old Firefox designs. ;)
Should be bug 1197954 - in other words, the Intel DDX driver does not work with the GLX Vsync source.
Ouch: bug 1279309 was even filed as regression:
(Andrew Comminos [:acomminos] from bug 1279309 comment 0)
On mesa drivers, changing the screen resolution with XRandR results in a hang in the GLX VSync thread- particularly when the change makes the root window larger.
I'm thinking recreating the GLX context backing the vsync source after the root window gets resized should fix this issue. This is what compton does.

The first version were we shipped hardware Webrender (and thus any hardware acceleration) on Linux was 84 (bug 1675766),
I can't seem to reproduce this on Gnome X11, not even when I change display resolution, not when I press F11.
but a large group of the affected users (of this bug) only got it in 89 (bug 1702301). So ESR 91 is certainly the first ESR which is affected.
- KDE
- loading animation and kde start menu flicker
- Firefox startup fine, broken unusable Firefox after F11 - can be fixed by leaving fullscreen
- Firefox fine after display resolution change, but KDE glitches occur (display configuration window is now displayed multiple times as part of the background image)
- reproducible with Xfce
- reports from MATE
I assume this bug could have been the cause for some of the reports in bug 1717105.

Confirmed: HW WR runs fine with layout.frame_rate:60 and 0. If possible, it would be enough to block GLX_SGI_video_sync as a separate feature.
(At the moment, users of the deprecated Intel driver can manually set gfx.webrender.all=true and layout.frame_rate=60 if they want HW WR back.)
