I have a similar problem, and I figured out that optifine caused this (to be honest I'm not surprised I was trying to use shaders previous to this and my computer doesn't have a graphics card so that went well...) but I would like to use optifine, I kinda rely on it to play the game at this point how do I fix this? I kinda want to have my cake and eat it too I guess.... I need it for its advanced settings and the zoom feature. please help!
