See bug #344359

We've basically two different possible causes here
a) a fast slide animation causes insufficient repaints
b) the old buffer isn't correctly cleared

(b) would resolve by running
   KWIN_USE_BUFFER_AGE=0 kwin_x11 --replace &

shouldnt the mentioned bug be "confirmed" then?

Nobody -at least not me- really cares about that flag =)

(I sometimes set it if I can explain a non-deterministic nor reproducible weird behavior from the code, but otherwise a bug is confirmed because it's confirmed, not because it's flagged CONFIRMED)
