Steps of reproduction

  1. Use picom
  2. It sometimes crashes. This is not the earlier realtime crash when unlocking the screen.

Other Details

I noticed it crashing earlier, so I rebuilt with what was then git head. So the crash was introduced before this or in something else (driver update?). Hard to say if it's nvidia or picom since I updated everything at once, including picom to some old git version from a few weeks ago since 11.2 is still crashy with the other crash.

yshui commented 3 months ago

hi do you have a stack trace?

awused commented 3 months ago

I've rebuilt it with --releasetype=debug and I'm waiting for it to crash again with --log-level debug. Could take a few hours or a few days.

@awused thanks! do you have more of that log?

yshui commented 3 months ago

hmm, i have a theory.

yshui commented 3 months ago

@awused try 4c5224a0ebee0ccd06c104dcdc297227ccba03a7 ae21c3df61b872010fdf3cb3d74e27e0468c6330

never mind, i don't think this is it.

yshui commented 3 months ago

@awused try https://github.com/yshui/picom/commit/c987b8c5a6416b453c89f5305e5a02bcb144f1e4

Unsure if this is it. I was pretty sloppy with the locks, and this fixes that.

awused commented 3 months ago

I've got the new code running but since I have no reliable way to reproduce this at will so it might take a while.

awused commented 3 months ago

Got a different crash, not sure if this is related or not. The crash itself is in a log_debug call but I assume it means some state is corrupt at that point.
