Bug#882980: blender: 3d view artifacts when selecting vertices, edges or faces

[Sergey Sharybin]

Hi,

Please try various values for "Window Draw Method" and "Selection" in
User Preferences -> System. Preferred windows draw method is Triple
Buffer, so start with explicitly using that instead of Automatic. And
see if any selection method makes things to work.

If that doesn't help, please test with official builds from
blender.org and see if the issue happens there.

If possible, it also worth testing if latest drivers from NVidia for
your GPU makes a difference.

Regards,
Sergey Sharybin
