Forgive me if there is a solution to this, but I haven't been able to find one. The ability to prevent the screen saver from starting during full screen apps would be a nice feature. Having the screen saver pop on during a movie is annoying, but if you do something like pause a Windows game you are testing in Wine to help your wife with something, bad things happen when the screen saver starts. For now my solution is to set screen saver to 200 minutes before starting a movie and now before starting a game.

I keep that set to never, because you can't set it for more than a hour.
The problem happened when the screensaver started not from the screen turning off. The screen was still on and the screensaver was running, but looked like 2 fps.
My settings in Menu - Settings - Screensaver (XScreenSaver 5.15) Display Mode tab Blank After = I change depending on what I'm doing from 15 for general use to 222 for video and now games. Cycle After = 1 Advanced tab Display Power Management section Standby After = 120 Suspend After = 180 Off After = 240
