The forum lost all of my post, twice, so typing it all again.

 

Intel IGU is the main display driver. (E3-1265L v3)  With the AMD driver installed for 7970 the KDE desktop still shows fine.  But when decoding video, only the top 1/16th of the display shows video.  The rest of the display is a frozen frame from early in the video.  Debian Testing.

 

Remove the AMD driver, and video display is fine.
