Hi,
There is a regression in Linux 5.10.9 that does not happen in 5.10.8. It is still there as
of 5.11.1
This regression consists in graphics artifacts that will *only* start appearing after resuming
from suspend. They don't happen immediately after resuming from suspend either, but
after some minutes.
My system has integrated intel graphics
00:02.0 VGA compatible controller: Intel Corporation 4th Generation Core Processor Family Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])
CPU: Intel(R) Core(TM) i3-4170T CPU @ 3.20GHz
For reference, this is the list of i915 commits that went into 5.10.9.
