--- Comment #66 from kdebuac....@porcupinefactory.org --- valdi...@gmail.com - this sounds like a kwin issue. Try doing `kwin --replace` and see if it goes away. Then perhaps it can be filed in the kwin category. I'm occasionally experiencing something similar on Ivy Bridge btw. -- You are receiving this mail because: You are watching all bug changes.
