I started experiencing flicker while playing videos in fullscreen after updating to xf86-video-intel-2.99.912. It occurs only with the opengl vo driver. Video files play fine with the xv driver.

Bisecting the issue lead me to the following commit in xf86-video-intel:
8369166349c92a20d9a2e7d0256e63f66fe2682b  sna/dri2: Enable immediate buffer exchanges

I am using an Asus EeePC 1000H with an intel 945GME and Arch linux. I've got the same issue with my mac mini ~2007 model, also a 945GM.

It can be reproduced using these commands:
mpv --no-config --vo=opengl-old <file>
mplayer -noconfig user -vo gl <file>
