X11 before suspend

SUMMARY
I noticed weird cursor movements and choppy scrolling in internet browser on my
system after
suspend/resume cycle. I enabled "Show fps" effect in "Desktop effects" kcm and
saw that frame rate drops from 60 to 45 on X11 and from 50 to 25 on Wayland
after suspend/resume cycle, as we can see in the attached screenshots.

STEPS TO REPRODUCE
1. start X11 session
2. suspend your system and wake up it
3. open any app (Kate, for example) and move cursor on it: cursor lags
4. do logout
5. start Wayland session
6. repeat the steps 2 and 3: cursor lags again

EXPECTED RESULT
frame rate should not change after suspend/resume cycle
