Confirmed, with a properly configured KDE panel (top of the screen, 
auto-hiding disabled, icon-zooming enabled). It's nice to have the big "K" 
logo in the top left corner of the screen when playing the demo game ;-)

I'd say it's typically a Windows bug. With KDE riddled with more and more 
eye-candy features like this icon-zooming, we will very likely run into such 
problems more and more frequently in the future.

The problem is the "hack" used when setting the fullscreen mode: is it really 
needed? All seems to work fine without it on my system.
