No fancy WebGL or animations. Just plain Bugzilla/Phabricator/Gmail/Matrix. IIRC, the crash was when switching from another app to Firefox on both occasions.

Which Mesa version are you using? Had that recently been updated? Is this reproducible at all?

Had that recently been updated?

No, but the kernel had an update on Dec 14th. The modules went from 5.4.0-54.60 to 5.4.0-58.64.

Is this reproducible at all?

I don't have any specific steps, unfortunately.

[Andrew Osmond [:aosmond] (he/him)]

We don't have device resets turned on yet with EGL. I wonder exactly how they manifest. Something to keep an eye on when I turn it on.

Comment 5

[Robert Mader [:rmader]]

Henry, do you still see this on stable and/or nightly?

Comment 6

[Henri Sivonen (:hsivonen) (temporarily away from Bugzilla)]

I haven't seen this in a while.

Thanks, closing then for now, please reopen if you run into it again.
