I may be wrong, but by what the text keeps repeating, I think it has to do with the Tessellator.

Were you teleporting too and from with waypoints? The tessellator may be causing an overload on chunk rendering. (May be wrong) If possible try removing it and see what happens. You may have to even go as far as reinstalling the mod it comes with. Hope this helps

i don't teleport anywhere actually i just fly with morph mod lol

i will try and re install optifine and see if that works out

it appears you minimap is incompatible with optifine or possibly one of the settings in it
