Recently got a new computer:
AMD Athlon x4 760K
Gigabyte Radeon R9 270X OC
8GB RAM

The problem occurs at above render distance >9 and to chunk that are not loaded. As you can see in the screenshot. Certain bits of terrain appear to tessellate, the bit of terrain seems to change randomly. Though not shown in screenshot, entities such as mobs tend to have very distorted meshes where certain vertices appear to stretch when in the proximity of the broken chunk. Note: The tessellated chunks appear to have no physics yet I haven't fully tried.

Not too much of a problem but I just decided to mention it.
