Description Wong Yong Jie 2013-07-04 22:25:06 UTC 
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.
