I am using the latest version of the GLSL shaders mod (v2.3.18 ), the latest version of Botania (v100). and forge version 1.7.10-10.13.0.1199

When a mana pool gets any mana in it, or after placing down a mana pylon, natura pylon or gaia pylon it sets of a visual glitch when using shaders. Some of the items affected are the vanilla chests and heads, mana spreaders and the petal apothecary. The blocks turn black and the darker parts of the block start reflecting the sky even when under a roof. Also specs of shadow appears on the ground and moves along the ground if the player moves within about 100 blocks of a pool or pylon. Tested with several mods, and on a fresh install with only Botania and GLSL installed.

I don't support the GLSL shades mod. Just turn off mine in the config. Might make it so it autodetects.

Figured as much when I read through the config and saw that option, but thought i might as well mention it just in case. Love your work on the mod so far, it has quickly become one of my favorites.
