The framedrop is always and most observable when enter and leave overview. It
drops from ~60 to ~30 when I enter overview. It then jumps between 60 to 30
when I'm in overview. If I move the any window inside overview, it goes back to
60. If I stop the input, framerate starts to jump again.

Sorry for my late reply. I cannot get screen recording and show the framerate
drop. It seems doing screen recording from OBS Studio somehow fix the issue. I
can use Show FPS in Desktop Effect to display the current FPS though.

In Plasma 6 RC1 (Rawhide.20240117.n.0), it is much improved compare to beta1
but little difference compare to beta2. The error message I reported in
previous post does not seem to appear anymore.
