Comment (by pbennett):

 You have a screen size of 1920x1080 and a video of 1280x720. You set the
 video mode to 1920x1080 which is the same size as the GUI mode.

 I just now tried exactly the same thing with MythTV master version and I
 see no black bar. The video is full screen.

 The changes I had originally made were to address the case where the
 resolution was changed. However in your case the resolution did not
 change.

 The image cannot be sitting on the bottom edge of the screen, some of it
 must be cut off, because at 1280x720 it is the same shape and size as the
 screen, or am I missing something here?

 If I can recreate the problem I expect I could fix it, but nothing I do
 creates this effect.

 If you change to use OpenGL playback profile, with standard decoding
 instead of VAAPI, does anything change?

 I assume if you disable the separate modes for video and GUI that the
 problem goes away?

 Could there be a broken OpenGL implementation? Perhaps some versions of
 OpenGL handle resolution changes differently?
