--- Comment #29 from Julien Delquié <julien....@gmail.com> ---
Same issue here.
Changing "Prefer efficiency” and “Prefer color accuracy" does not change
anything.
Changing "Adaptive sync" seems to remove screen corruption but does not remove
duplicate mouse.
Lowering refresh rate from 240 Hz to 144 Hz (and without adaptive sync, and
with Prefer efficiency) seams to be a workaround for my setup.
Thus, I didn’t tried KWIN_FORCE_SW_CURSOR=1 workaround.
