Summary0000434: When using vdpau hardware decode, ensure that the OpenGL driver does not interfere.
DescriptionIf you use vdpau hardware decode on Big Bucks Bunny which is 60fps, and your Settings-Preferences, Playback A, Video Driver is set to X11, the "Play every frame" shows it is playing at 60fps. However, when you switch to a Video Driver of "X11-OpenGL", it only runs at 13fps on Ubuntu 20 and Fedora 29. So it must be thrashing.

I notice this fall of fps even without setting vdpau. I remember that Adam Williams had also noticed this difference between X11 and X11-OpenGL and said he would examine the problem. But in later releases of Cin-HV he didn't mention it again.
However, when using various plugins it is important to use OpenGL, so finding a solution would be desirable.
