Please ask for help in a forum of your distribution with correct OpenGL driver installation.

A more recent version of the nvidia driver is installed.  There is an even newer one I will try updating and see if it works.

Ok so I got it working.  I had to purge all my libqt* and did a post-autoremove just for good measure, which also happened to remove kdenlive itself, then reinstalled kdenlive.  I suspect it may have had something to do with qt4 and 5 not playing nice with one another.  The OpenGL driver is part of the NVIDIA packages, so it most likely had nothing to do with that.
