I have not noticed this in Ubuntu 14.04.1 until now because I had previous been using Openbox (LXDE Desktop Environment), but after switching back to Unity I noticed this.
I haven't seen any issues prior with any OpenGL programs under the LXDE Desktop Environment nor so far any artifacts/glitches in OpenGL software on Unity. In my case it has nothing to do with Video memory (only about 23% used, hovering at about 9% GPU Utilization), as far as I can tell, this is not an NVIDIA bug, but a compiz bug.
