It's hard to explain what is happening so here's a picture:
Sorry that it looks like it was taken with a potato (Looks better in attachments) but as you can see, blocks are trying to appear 3D on a 2D screen. The items in my inventory are also very grey, and everything else is just tinted grey. I've tried changing the visual options but nothing works. I also don't know if i should go to the devs with this, or if its just a visual glitch.
