[nvidia] Screen displays weird broken animation behavior when I unlock

[Jonathan Kamens]

I sat down at my computer this morning and unlocked the screen and saw the behavior shown in the attached video. I waited a while and it never stopped. I hit Alt-L to lock the screen again which worked, and then unlocked it again, which worked.

Please run:

  lspci -k > lspcik.txt
  journalctl -b0 > journal.txt
  dmesg > dmesg.txt

and then attach those three files.

Please also try uninstalling (don't just turn them off) these extensions:

'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'

Then reboot. Does the problem still occur?

We need to try this because extensions cause a large number of bugs in gnome-shell and the lock screen is part of gnome-shell.

If I see it happen again I will do that, because then it would be a meaningful test, but so far I've only seen this happen once, so unless it happens again so we can get some idea of how frequent it is, the inconvenience of removing the extensions -- which I use every day -- for an indeterminate period of time is not justified.
