I seem to be having two issues with all lights in Project Red. The first of these (Picture 1) is one that has been a problem for a while. In the first-person view when looking at the lamp in your hand, there is a "texture map" if that makes sense. The second has to do with when lights are placed in the world. They have a red circle on the outside layer of the block texture. This happens without any resource packs enabled. I use OptiFine, FWIW.

First thing to try is removing optifine. It often causes graphical weirdness.

OK.

Removing OptiFine solved the issue, but my performance takes a heavy hit, not to mention disabling shaders.
