1739780 - MOZ_WEBRENDER=1/GNOME Wayland/Nvidia/Fedora 35: Crash: "error 7: failed to import supplied dmabufs: Arguments are inconsistent (for example, a valid context requires buffers not supplied by a" (Fixed by downgrading to egl-wayland-1.1.7-2)

Status: RESOLVED MOVED

(Core :: Widget: Gtk, defect)

Description

[Pavel Sobolev]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Running firefox in the terminal yields the following:

[GFX1-]: No GPUs detected via PCI
[GFX1-]: glxtest: process failed (received signal 11)

These are just warnings, and Firefox starts as expected.

However, running MOZ_WEBRENDER=1 firefox crashes the browser.

Actual results:

Here's what the latter command yields:

[GFX1-]: No GPUs detected via PCI
[GFX1-]: glxtest: process failed (received signal 11)
ExceptionHandler::GenerateDump cloned child 206173
ExceptionHandler::SendContinueSignalToChild sent continue signal to child
ExceptionHandler::WaitForContinueSignal waiting for continue signal...
Exiting due to channel error.

Reproducible on new profiles.

Here's the ID of the crash report: bp-abfa1cd3-5ec7-41c5-b484-d2bbe0211106.

Expected results:

Firefox should not crash, and WebRender should work.

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

Thanks for the report!
Please install mesa-utils-extra (Fedora: $ sudo dnf install egl-utils), copy the output of $ eglinfo and $ es2_info and paste it here.

Please try downgrading egl-wayland.

(Thomas Roder from bug 1739599 comment 3)

Downgrade to egl-wayland-1.1.7-2 fixes the problem. Since other programs (evolution, gnome-maps...) are also affected, it's probably an egl issue, not Firefox.

Sorry for wasting your time.

Aight, it all comes down to issues with egl-wayland. Thanks for looking into it, downgrading the egl-wayland package worked. I think bug 1739783 is the same as this one and, hence, should be closed, too.
