--- Comment #56 from wolfyrion <kyria...@mypcrevolution.com> --- some more investigation... 1. ALL opengl games/applications disable compositor but actually some of them break kwin compositor. 2. if I use the org.kde.oxygen decoration it doesnt give me any artifacts 3. After opening a game or application that it will break the compositor even when the compositor is enabled. When the compositor/kwin is breaks what ever I open after it creates black squares all over the screen Image http://i.imgur.com/5gH0ZAv.png ( I cant find any attachment button when I post any bug so I am using imgur) 4. I have noticed that when a game breaks KWIN compositor it seems that VSYNC is messed up because I can see a lot of tearing issues in the game when the compositor is messed up. Dont know if that is because NVIDIA or KWIN but it seems like they have a conflict somewhere 5. In order to fix this problem I had to install another compositor like for example compiz. So whenever a game or an application breaks the compositor I just enable compiz for a sec and then activate again KWIN compositor and I am back to normal. -- You are receiving this mail because: You are watching all bug changes.
