--- Comment #1 from Oxalica <oxal...@pm.me> ---
After some debugging, I made it work with the following patch on top of kwin
v6.2.4. With it, both spectacle and obs-studio record the non-scaled correct
resolution and the content looks clear. I hope it helps, but I'm not sure if
it's ideal and it's not applicable on kwin master due to some non-trivial code
change.
