SUMMARY
I have an i5-1235U with onboard Intel Iris Xe graphics. With the latest update
to plasma 6.1, there have been massive frame drops (into the 30ish fps) and
reduced performance in graphics situations in general. Most of the time the
frame rate does stay at 60, but the drops are frequent, about every 15-20
seconds. I am sorry I cannot attach the fps graph since I cannot capture the
show fps applet in video. This only used to happen in the x11 session but now
it also occurs in the wayland session. I think this has something to do with
triple buffering but I am not really sure.
STEPS TO REPRODUCE
1. Have Intel Iris Xe graphics
2. Enable the show fps option in kwin
3. See the Current FPS
OBSERVED RESULT
There should be no frame drops.
EXPECTED RESULT
Frame drops every 15-20 seconds.
