Significant blocking artifacts with VAAPI

Description
Attempting to use the VAAPI acceleration support with an AMD Vega GPU is showing significant blocking artifacts that are not part of the original video source. I've attached a couple of screenshots from the same TV recording, one with VAAPI enabled and the other with the standard OpenGL renderer.
This is a Vega 56 GPU on a ppc64le host.

In V30 there is a new rewritten VAAPI2. Also coming in V31 will be a rewritten OpenGL renderer. These will likely change what you see, hopefully for the better. I recommend upgrading to V30 and trying VAAPI and VAAPI2 there.

VAAPI support has been substantially re-written in master and should now be far more complete. I can't reproduce this issue.
If there are still issues in master (or 0.31 when it is released), please open another ticket and attach a full log from:
mythfrontend -v playback,gpu
If the issue is specific to certain file, then please attach a short clip that shows the problem on your system.
