Not using neither texture packs nor things like otpifine, not needed with my specs and i'm not using shader packs so..
The doors without textures that you can see on the screenshot are the vanilla doors only (Oak, Iron, Spruce, Birch, Jungle, Acacia and Dark Oak) I've checked.
I've put some doors on the ground and in the belt just so you can see.
OK, I'm also now getting the same issue. I'll look into it for 0.11.2.
0.11.1 has been released, with many fixes, changes, and tweaks. Check out the changelog ingame.
