I can confirm the same issue with my system, using an NVIDIA 660 GTX, running Mint 17 with Nvidia drivers 331.38. Turning off FXAA didn't work for me. None of the settings made a difference. The only thing worked was removing the NVIDIA settings file as suggested by xavier zinn. Now everything seems to be running flawlessly.
