OK, I upgraded to CVS yesterday (3/15) and still the same thing.  My 
OpenGL implementation is fine (see above); TuxRacer & glxgears run just 
fine; I use the Goom visualization in MythMusic without problems.  It's 
just the MythGallery slideshow transitions.  Since AFAIK MythGallery 
hasn't changed since I last had it working, and since I have done a 
bare-metal install since then, I'm starting to suspect Qt.  Am I right 
in thinking that MythGallery is currently the only module using 
QGLWidget for its OpenGL stuff (I assume Goom doesn't, as that's 
captured from another project, and I'm pretty sure TuxRacer & glxgears 
don't use Qt).

On my old box I was using Qt built from source (for a long time it was 
3.1.2, but I may have upgraded to the 3.2.x series at some point... I 
don't recall).  Now I'm using the qt-3.2.3-0.fdr.8.1 RPM from 
kde-redhat.  I see that theres a qt-3.2.3-0.fdr.9.1 available; don't 
know if that would make a difference.  Looking at my ${QTDIR}/
pkgconfig/qt-mt.prc file, it looks like Qt was configured with 
'opengl'... I dunno, I'm grasping at straws here.

Anyone running Fedora w/binary Nvidia graphics drivers have working 
OpenGL transitions in MythGallery?  If so, what Qt package are you
