I'm testing out the new DPM patches on drm-next-3.11. When there is heavy screen updates (i.e. dragging windows around), screen corruption appears (see video). DPM otherwise works perfectly; system runs cooler and UVD also works perfectly fine. Corruption does not occur with radeon.dpm off. There is nothing unusual in the kernel logs. I can provide more info if requested. Video link: http://www.youtube.com/watch?v=WaWHBckwPpo&feature=youtu.be

Should be fixed with this commit: http://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-next-3.11&id=222dc9a072e27b5069a7c03738e360eafdc2fdf5
Thanks! :D Building and testing it out, will report back when I'm done.
I can confirm that the issue has been resolved. Thanks!
