Hi guys. I have a very strange issue, if I try to play videos using vdpau or
vaapi, I get graphical corruption. This only happens after I try to make if
fullscreen once. After that, fullscreen and windowed are corrupted. If i were
to never make it fullscreen, the video would work fine. There is no issue if I
remove Option "DRI3"(eg. use DRI2), if I use modesetting DRI3, or if I disable
vdpau/vaapi.

Here is a video of the corruption: https://www.youtube.com/watch?v=o8va0gNMrnU


Here is some relevant info from MrCooper: "I guess it's some bad interaction
between DRI3 and DRI2 page flipping"

I am using gentoo with xf86-video-ati git, xserver git, kernel 3.19, and the
Cinnamon DE with Muffin WM.

I can test any patches or provide more info upon request,

Thanks alot,
sarnex
