My edges/faces disappear at random in viewport

Hi, Im wondering if someone else has this error at times when I select a vertex or a face my edges disappear at random, they appear back if i change my pov or if I click any other face, or of I click certain tick boxes that are unrelated to the mesh, so if this happens and for example I click on the grid box ticker then the model displays correctly.

This is kind of driving me nuts, so if anyone knows how to fix it do tell

I just found out if i set the display to be “texture solid” then this error does not happens, so I can work like this, however I wonder why this is happening when this is disabled.

I am having the exact same issue on Gentoo linux with blender 2.63.17, 64 bit, compiled from svn. This is not specific to this version only, because I am noticing this since some time ago (after 2.5, but when exactly this started I can’t say). I have the same video card.
