Hi, perhaps one of the experts can answer this in a few words...
SandyBridge can prevent tearing only by using pageflipping.
pageflipping on Xorg always flips the whole framebuffer, so it can only
be synced to one output device.
The vaapi-enabled MPlayer plays nice in fullscreen mode (via vaapi or
gl), but sometimes tears in windowed mode.
Is this a MPlayer, Xorg, intel driver or SandyBridge problem? It's clear
that pageflipping can not be syncronized to two displays at once, but I
see no theoretical need for a video being fullscreen to make use of
pageflipping.
Thank you for any hints!
Greets,
Kiste
