When I click the launcher icon of a window that is already selected (usually by accident) the screen will freeze for 5-20 seconds and then usually a popup will appear saying that a system error was detected:

compiz crashed with SIGSEGV in ScaleScreen::getWindows[abi:cxx11]()

Sometimes after this crash when the screen returns to normal the launcher bar is all blacked out with no color as if the screen were frozen, even though it no longer is. This weird behavior will last until I restart.

Has anyone experienced this and found a solution?

  1. Install compizconfig-settings-manager and run it
  2. Change the settings as follows:

    • General → OpenGL → Texture Filter = Fast
    • Sync To Vblank = uncheck
    • Effects &rightarr; Animations = uncheck
    • Effects → Fading Windows = uncheck
  3. Reboot

Hope this helps. (Sorry for the raw text as writing on phone.)
