If you think it's a false positive, please remove "OpenGLIsUnsafe" > from [Compositing] in kwinrc and restart kwin. > kwin_core: Compositing is not possible So what happened here was that KWin crashed five times in a row while trying to do compositing and therefore decided that compositing was unstable and disabled it. The Present Windows effect requires compositing, so it stopped working, with no explanation. This is ultimately caused by Bug 452344; we'll discuss a fix there. *** This bug has been marked as a duplicate of bug 452344 *** -- You are receiving this mail because: You are watching all bug changes.
