Alright well for some reason my minecraft started glitching out and theres these sudden flickeres where the floor around me becomes transparent and i can see the cave system beneath me, it happens here and there and is pretty annoying, the only mods im using is optifine, anyone know what would be causing this? or how to fix it? id like to enjoy my minecraft so please help me out thanks. oh and theres also these little lag spikes that come with it even though im getting well over 100 fps, i just capped it at 100, just adding that in there.
Glitches and flickers of disappearing blocks.
