1900495 - Firefox 126 crash in [@ @0x0 | st_pbo_draw ] in Mesa 24.1.0 with Intel + Nvidia dualGPU

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[heitorrdpp]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

Firefox started randomly crashing after 126 update. It may be just an impression but I think using YouTube the crashes are more frequent.

Actual results:

Firefox would simply crash and close the browser.

Expected results:

Firefox should not crash for no reason.

I am on a fresh install of EndeavourOS and only using UBlockOrigin extension.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for the report!
Please check if starting Firefox with MOZ_ENABLE_WAYLAND=0 environment variable (or never switching to the Nvidia GPU) avoids the crash. Then it would likely be bug 1898476.
$ MOZ_ENABLE_WAYLAND=0 path/to/firefox

The bug has a crash signature, thus the bug will be considered confirmed.

Thank you for the reply! So I tested it for a couple of minutes with the variable set, didn't have any crashes yet, but I am not sure if it is a firefox related issue anymore, since KWin also started crashing. And from what I could tell both crashes are on the Intel GPU actually. I am trying to troubleshoot at the moment, but I don't have much experience with this type of thing.

The bug still happens on Nobara Linux 39
Running with MOZ_ENABLE_WAYLAND=0 the performance on videos is terrible, completely unusable.
When I ran it with MOZ_ENABLE_WAYLAND=0 it outputed:

The glxtest message wasn't present before.
Also the KWin crashes stopped happening on Nobara, which makes me believe I was having two different problems simultaneously on Endeavour.
Talking to people online, they also seem to be having problems with firefox 126 on videos supposedly, so maybe this is actually an issue with firefox?

It may be related to Bug 1902589 - Multi GPU crashes on Mesa 24.0.7+

Closing because no crashes reported for 12 weeks.
