rgl

EXACTLY!!! I use the NVidia drivers from their site, and that is exactly what happened. I reinstalled mesa-libGL.x86_64 and that resolved the issue (though not sure if that broke anything else on the workstation that relies on the NVidia drivers)

NVIDIA has a fork of libGL that is optimized for their driver. You may
wish to figure out how to replace the mesa-libGL libraries with their
copy. If memory serves, they put their libGL library in a different
directory (then remove the system copy).
