Screen flickering on Radeon 680M - 6.12
Brief summary of the problem:
This was originally reported in https://bugzilla.kernel.org/show_bug.cgi?id=219468
Random screen flickering is observed after upgrading to 6.12 (from rc1), which was not observed in 6.11 kernels. The phenomenon is more notable when trying to scroll the screen with mouse. Seen on a machine running KDE Plasma 6.2 (w/ wayland) on Arch Linux. Other WMs have not been tested.
I could identify nothing special from dmesg.
