Nvidia driver fixed the problem. Thank you El Repo! Where do I send you $10? (Seriously. This saved me so much time.)

If you just want an easy solution you could try the nvidia drivers from elrepo. Start with nvidia-detect to find out which version you need, as explained here:

I have finally received and am configuring my new workstations eith the NVS510 graphics cards, and have run into rather a problem. The X server seems to be loading the NOUVEAU driver properly (based on the contents of Xorg.0.log), but I have one X11 application that doesn't work correctly; it runs as though XSynchronized is always True, even though it's explicitly set to False in the code. In other words, its redraw behavior is god-awful; worse because it auto-redraws once per second for little apparent reason. And some of the windows draw with artifacts if they're covered and uncovered.
Any ideas, anyone? I will gladly provide more info on request, but I'm not an expert X11 programmer (worse, this application uses a third party wrapper library). This is definitely new behavior on this new computer (the previous computers, also using the Nouveau driver with GeForce 7600 cards, did not seem to have this behavior).
