I have a similar problem, which I was just able to fix.  I was given 
some clues from an earlier thread about Time Stretching.  Balaji Ramani 
told me to recompile (or download his RPMs) WITHOUT opengl_vsync.  I did 
this and it works perfectly.  Not sure what is broken in .17, but it has 
something to do with the opengl_vsync.  I suppose it might be the new 
NVidia drivers too, but I thought I installed those before I upgraded to 
.17.  This is definitely worth a try.
