Description Nick Sarnie 2015-03-25 04:01:26 UTC 
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

    DRI2: Use radeon_get_pixmap_handle
    
    Now we can share pixmaps with no struct radeon_bo via DRI2.
    
    Fixes VDPAU video playback freezing when using an OpenGL compositor with
    DRI3 enabled.
