Nov 16, 2014 at 9:35 comment added legends2k Hey, I tried your suggestion and it seems to work! My near and far were 0.001f and 5000.0f, changing them to 100.0f and 2000.0f makes the issue vanish. Could you please post this as an answer and some material for me to read on this to understand the reason clearly?
Nov 16, 2014 at 9:13 comment added Qwerty it could be Z-fighting (depth buffer conflict). Z buffer usually has quite low depth resolution, so if your far plane is far, and you are far away from it, the faraway bins of the depth buffer will include a lot of space. You could try turning backface cull on; increasing depth buffer resolution; or making the far plane closer.
