Comment 6 for bug 1046664

I have a similar experience with this unredirected fullscreen windows option. It causes tearing in fullscreen flash when hardware acceleration is disabled. When it is enabled, there is no tearing but the player often crashes by changing between fs and windowed mode.
Also, smplayer flickers and/or crashes in fullscreen when the control bar shows up by pointing the mouse cursor to the bottom of the screen. This happens only if vdpau is selected as video output.
I'm using nvidia driver 310.19.
I wasn't aware that the unredirected fullscreen windows option is enabled by default in the latest revs, so I disabled it and now everything is back to normal.
