Public bug reported:
I am experiencing intermittent pixel corruption and flickering artifacts
in the background/desktop UI after updating to kernel version 7.0.0-38.
Behavior:
Random pixels/artifacts briefly flicker in the background from time
to time.
This issue was NOT present in kernel 7.0.0-34.
The issue started immediately after updating to kernel 7.0.0-38.
CPU: AMD Ryzen 5 9600X (12) @ 5.49 GHz
GPU: AMD Radeon RX 9060 XT 16 GB[Discrete]
P.S. I was planning to upgrade to the 26.10 beta this weekend, but I
will stay on Resolute to help resolve this issue with any testing you
might need. Thank you very much.
