Data point from last night

One of the other threads I'm currently involved with sent me to this page.


Last night I installed an updated copy of blootube via the svn trunk themes.

svn co http://svn.mythtv.org/svn/trunk/themes
cd themes
qmake themes.pro
sudo make install

mythfrontend -O Themepainter=opengl -O Theme=blootube-wide

Notice I forced the opengl painter.

What do you know, it worked.  This go me wondering if my myththemes 
install is too old.  I don't know if I've updated it since the original 
install and I know there was some work done on opengl and the myththemes 
  because of disappearing menu items as the user passes over them.

Maybe I'll give it a try tonight.  FYI I still don't like opengl 
themepainting.  It gives the appearance of being slow, do to the fading. 
  I think when I'm done playing I'll switch back to the quick snaps of 
qt.  Nice to know it works though.
