As mentioned earlier on I had a problem when I ran the Digestoeriods demo where when I quite the game the desktop did not redraw and I was left with a mess on the screen. I had to launch an app and drag it around the screen the get it back.
I have that same problem too. Might need a mention in the bug forums if it turns out to be quite common.
Do your screensavers have the same problem ?
Not that I noticed, but I generally don't have screensavers enabled and only use one of the OGL ones to check that I have successfully installed the 3D drivers. Can't check at the moment, as I'm in Vista currently.
maybe there is a way for an app to tell combiz to effectively disable itself for your app when its running fullscreen
Maybe, but that's out of my league, as I generally use code posted by the more knowledgeable around here for anything API related.
For the time being I'm just going to suggest that users disable and fancy eye-candy if they experience choppy screen updates in full-screen mode. If there's no way around it other than telling the user to manually disable these effects, then I may have the game default to windowed mode under Linux.
