--- Comment #3 from Lukas Sabota <lu...@lwsabota.com> --- I use both kwin_x11 as just a window manager and I also use it as a window manager and compositing manager: because they both seem to work exceptionally well. I was pleasantly surprised to see how well the compositing effects (such as the META+W overview / virtual desktop animations / transparency effects) worked with kwin_x11 in standalone mode. There did appear to be some very minor artifacting during the transition to overview mode, but it didn't prevent overview from functioning at all. Running kwin_x11 will exhibit this black background behavior both when compositing is enabled, and it's when disabled. I also couldn't seem to find where in kwin source code that the root window gets painted black. I've been doing some trial and error with gdb when I've had a spare chance, but haven't yet been able to dedicate much time to investigating. -- You are receiving this mail because: You are watching all bug changes.
