Created attachment 307141 [details] dmesg 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. My English is not so good for describing the problem exactly. So I link two clips where the display was taken. I could identify nothing special from dmesg. The dmesg and kernel configuration are attached.
