On Intel LNL, after screen is inverted by "gnome-randr modify eDP-1 --rotate
inverted"
Move cursor, the screen will get flicker, with the error in dmesg:
xe 0000:00:02.0: [drm] ERROR Fault errors on pipe A: 0x00040080

Intel provided a patch to fix it.
https://patchwork.freedesktop.org/patch/627668/?series=136033&rev=4

Tested on Intel LNL and MTL, screens are normal on all rotate mode,
and suspend/resume for 100 times on both LNL and MTL with positive results.

It may break i915 and xe driver.
Plucky should get this fix on 6.14.
SRU for oem-6.11 only which supports LNL.
