Could this be a duplicate of bug #177495

Comment 2 peto.milan 2010-12-02 22:22:10 UTC

yes thanks for link with this bug. Its second comment really helped for me :

> You can disable unredirecting the following way:
> 1. open ~/.kde/share/config/kwinrc in an editor
> 2. go to section [Compositing]
> 3. Add following line:
> UnredirectFullscreen=false
> 4. Save file and restart kwin (alt+f2 and kwin --replace)
