Created attachment 144969 [details] video artifacts. Hi everyone! I'm having graphical artifacts sometimes on my Xiaomi 12.5 inch laptop, running Kubuntu 18.04. It appears randomly after a half a day of working. To remove the artifact, I can close the application window it frames around. I use i915 intel integrated video. I've tried to enable/disable compositing and chose different OpenGL backends, nothing helped. Please see the attached screenshot. Also, I can provide more logs is required. Thanks in advance!
Looks more render compression related than display. Could you attach Xorg.0.log and glxinfo?

19.0.2... Distant bells are being rung, I think this style of corruption been seen before. Worth checking to see if there a 19.2 (or master) package of mesa available for testing.
Still 19.1.2 - is the latest for the latest Ubuntu version(eoan)

Check your xserver version. Bugs have been recently fixed: https://gitlab.freedesktop.org/xorg/xserver/issues/545

Bugs have been recently fixed: > > https://gitlab.freedesktop.org/xorg/xserver/issues/545 One of the bug there was worked around by a change in mutter. So there is still an annoying issue in i965 at the moment. The pattern looks like a desynchro in compressed state of the texture used for the decorations of the window. Does this happen after a screenshot was taken by any chance? :)

Hi Lionel! My working day has just begun, and I'll try to wait for a couple more days to try to see the artifact. At the moment - everything is fine so far...
Thanks Loinel and Chris! No artifacts so far. Thanks much! I'll take one more week to see...
