I'm having the same problem with things jumping out of fullscreen and have had for some time.
I'm running 8.04 with a Radeon 9250 using the open source drivers, AMD Athlon 2000 cpu, and "Normal" Desktop Effects enabled. Games affected (that I've tried) include SuperTux, Trigger, WormUX, NeverPutt, Pingus. It usually happens every 5-10 minutes or so. It's pretty annoying, as you have to click back into the game with the mouse to regain control of it, plus you lose a few seconds to a blank screen while it switches. This is fairly critical if you're playing a real-time game. Can confirm that turning Compiz off seems to fix it. -- [gutsy] sdl games leave fullscreen mode without obvious reason https://bugs.launchpad.net/bugs/155263 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
