[MC-61011] Transparent Textures - a cube of the world is invisible

I have attached a video that displays the bug:

In short, there is a cube (approximately 16 high by 30 long) that has rendered invisible. On switching of texturepack, it seems to fix itself. Has happened 3x since this video, 2 with texture pack, 1 without - all with OpenGL set to ON.

A much larger section missing in the screenshots. I thought it was a chunk loading error at first, but the blocks are still there and fully functional! I was almost burnt to death by lava that I had no idea existed! Underwater drowning also happened. This doesn't seem to be a chunk loading issue due to size as well, since the dimensions are 3D.

I have yet to see it replicated with OpenGL OFF. I assumed this may be the video card's fault, so I updated the drivers and problem persists...

Error not observed in previous snapshots or current version of MC.

Thoughts?
