Dear Pymol-Users,

I have a rather strange error. I can open pymol without having any problems or warnings. 
But when I'm looking at a protein then - especially when it is in cartoon mode, and even more when i move it around a lot - it is getting more and more blurry and it seems as if there are many small black spots on my protein. When I have more proteins aligned in different colors then I also see spots in the different colors on the protein. Has this problem occured to anyone else before? Does anyone know a solution to this problem?

My pymol version is PyMOL 1.4.1, I'm running it on Ubuntu 11.10 64bit, and my graphical card is Intel Corporation 2nd Generation Core Processor Family.

Best Regards, Julian
