I'm not sure what you mean by regress to a smaller window.
I use a quite "oldish" version of nvidia drivers: 260.19.36 (though
same issue with latest 290.10).
At least one other mythtv user has reported the same problem with
1.0.25, not sure what his video/audio card is ...

Do you want me to compile alsa back to those release and see if
anything makes any difference?
Can certainly do so...
