https://bugs.kde.org/show_bug.cgi?id=361154 --- Comment #63 from wolfyrion --- updating... 1. my friend with Arch who downgrade kwin still has the problem (my apologies) 2. Without running any game or any opengl application - just disabling and enabling the compositor (alt+shift + f12) many times with delay 2-3 secs is causing the problem/corruption. 3. The compositor needed to be enabled when launching games or apps for tearing issues etc.if for example the compositor is disabled export __GL_YIELD="USLEEP" or "TripleBuffer" "True" are not working. so atm I am using (alt+shift + f12) while I am ingame and xrender when I am out in order no to see the corrupted shadows. IS not the option that I want because I cant use any kwin effects but since I have no choice I am settled with that. 4. It has been a month and this bug is still unconfirmed somehow. Actually it should be on urgent list. Anyway my apologies for posting too much, this is my last post concerning this bug. Plasma 5 is the best DE and would appreciate any fix related to this this bug. -- You are receiving this mail because: You are watching all bug changes.
