Comment (by pbennett):

 Replying to [comment:23 Steven Ellis <support@…>]:
 > Is there any other debug data I can grab to help resolve this, or
 perhaps add some additional debug output to my local build?

 If you look at
 [changeset:"7388b5a60c54d5e812a535bf5212295e512c5c3f/mythtv"]:

 See the changes to mythtv/libs/libmythtv/videoout_opengl.cpp at the lines
 of code shown below. This is where I adjust for the resolution change.

 If you print out all the values in this calculation, maybe we can see what
 is going on

 {{{
 if (dvr.height() < mainSize.height())
     dvr.setTop(dvr.top()-mainSize.height()+dvr.height());
 }}}

 i.e. print dvr.height(), mainSize.height(), dvr.top() before the if test.
 Then after the calculation print dvr.top() again to see how it was
 changed. If you give me the results also tell me the screen resolutions
 you are using at the time.
