1682661 - Repeatable corruption and crashes in FF 84 with gfx.webrender.all = true on Linux nVidia

Status: RESOLVED DUPLICATE of bug 1683266

(Core :: Graphics: WebRender, defect, P3)

Description

[Jonathan Sambrook]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:84.0) Gecko/20100101 Firefox/84.0

Steps to reproduce:

Run FF84 in X11 on VT7.
Change to VT3.
Change back to VT7.

(I tried in SafeMode, but that disables WebRender

Actual results:

Sometimes corruption (see attache image) followed by a crash.

More commonly a straight off crash.

If I set gfx.webrender.all = false, then there's no problem.

I tried setting the envvar MOZ_X11_EGL=1, but that lead to immediate gui glitches.

A colleague confirms the issue.

Comment 3

[Darkspirit]

Thanks for the report!
I assume VT switching (switching between the other text consoles and VT7 with X11) is similar to suspend and resume.

The crash should be fixed by updating the Nvidia driver to at least 455.28 which contains an important bug fix (bug 1656361 comment 9).

The corruption should be fixed by manually configuring the driver:
(Oliver from bug 1515253 comment 18)

After RTFM at https://download.nvidia.com/XFree86/Linux-x86_64/455.28/README/powermanagement.html#SystemdConfigur74e29 and following the instructions (e.g. set NVreg_PreserveVideoMemoryAllocations=1 and sudo systemctl enable ...) I was able to restore my Firefox window successfully after resume.

Comment 4

[Jonathan Sambrook]

I've updated to 455.45.01, added NVreg_PreserveVideoMemoryAllocations=1 (and confirmed it's active after a reboot with grep PreserveVideoMemoryAllocations /proc/driver/nvidia/params), and installed the systemd related items.

Sadly I'm still seeing crashes.

Comment 5

[Jamie Nicol [:jnicol]]

Did any of the crashes submit crash reports? You can check by navigating to about:crashes. Please post the links to any here if you can. Thanks.

Comment 6

[Darkspirit]

I am able to reproduce this: bug 1683266 comment 10
