If you have problems with fullscreen applications flickering when desktop effects are enabled then you can try the following solution, which was suggested in KDE Bug 177495:

  • Open ~/.kde/share/config/kwinrc in an editor (where ~ stands for your home directory).
  • Go to the section [Compositing].
  • Add the following line:
UnredirectFullscreen=false
  • Save the file.
  • Apply the changes by pressing Alt+F2 and running:
qdbus org.kde.kwin /KWin reconfigure

This forces KWin not to use window unredirection but can affect performance of fullscreen OpenGL applications when desktop effects are enabled. Desktop effects can be suspended to prevent performance issues (press Alt+Shift+F12) when running such applications.
