Comment (by Jonatan <mythtv@…>):

 I am still seeing this with r26598.  See log excerpts with -v playback
 below and attached logs.  I added a log like "QEvent::Resize(<width>,
 <height>)" of any resize events received in tv_play.cpp.

 I am using Qt 4.6.2 if it has any relevance.

 As you mention, OpenGL playback also has a similar problem but with a
 different display rect it seems.

 The display resolution has changed to 720x576 prior to the point where the
 excerpts were taken.

 Trunk behavior:
 {{{

 end ok

 }}}

 Behavior with fix mentioned in comment comment:4, and attached patch:
