Hi, Same issue there. However I noticed the two following things : - The problem is much less present if you uncheck the experimental kwin feature which allows apps to disable compositiong. This option should be unchecked by default. (In system settings go to the display section, then compositing) - If you have 2 users on different X sessions it appears a bit again. - Anyway Kwin looks quite unstable as of now and the issue should be fixed by the release time.
