I have this problem when I run pymol using the Intel driver on my Ubuntu
11.10 64bit machine. However, if I fire it up using the nvidia driver, I
have no issues and it's very smooth. As someone else mentioned, this is
likely due to the poor quality of Intel Sandy Bridge graphics chips.
Here are my cards:
Intel mobile - i915 driver
Nvidia geforce gt 520m - nvidia-280.13-0ubuntu6 driver
I use ironhide to run the nvidia card for graphics intensive programs
