Most user comments point to watching a video and possibly scrolling the page while doing so. Note that there are other crashes under this signature but with a different crash reason and none of the other types of crash have comments mentioning videos so they're very likely unrelated.

There are several crash reports where the users mention that this happens when clicking the picture-in-picture button on a video.

There are several crash reports where the users mention that this happens when clicking the picture-in-picture button on a video.

If there's any need for confirmation I can reproduce the issue reliably.

Main GPU is AMD with all monitors (1xHiDPI and 2xLowDPI) connected. I start Firefox on the iGPU with a complete fresh profile:

DRI_PRIME=1 LIBVA_DRIVER_NAME=iHD firefox-beta -P debugTest

Creating a new window in any fashion (PiP, new window, extension-popup) results in a crash. For example (video of action):

Looks like Wayland compositor bug.

Comment 4

[BugBot [:suhaib / :marco/ :calixte]]

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.

Closing because no crashes reported for 12 weeks.
