Just a few hours ago. When I open the game, instead of "Mojang" being
lit up it's just black, eventually going non-responsive and
gray-screening. After individually removing every mod, resource pack,
and shader I have, I have determined the only thing wrong is optifine. I
tried fresh installing it, and the same thing happens. Earlier this day
I installed "SetPriority" and the problems began after that, but I
deleted and the problem continues. I doubt its related.
