GDM crashes sometimes when switching windows right after opening a new window

[Ciro Santilli 六四事件 法轮功]

Crash at: https://errors.ubuntu.com/oops/8a56d4be-6d35-11ec-824f-fa163e6cac46

This has happened a few times, I open the VLC media player to play some music, and then immediately alt tab to get back to the browser, while the window appears to be "still opening".

The result then is that things like Alt + Tab stop working, and I see a gdm crash under /var/crash ,

It is not very easy to reproduce due to timing. I started getting this after upgrading to 21.10.

Running NVIDIA driver 470.86, gdm3 is at 41~rc-0ubuntu2.

Thanks for the bug report.

Unfortunately https://errors.ubuntu.com/oops/8a56d4be-6d35-11ec-824f-fa163e6cac46 does not have any details of what in gdm3 crashed, only that it was a SIGSEGV.

Please try following these instructions to look for more reports of the same bug: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment
