I might have found something that leads to the solution. My GPU was overclocked to the max it could handle, which is what i thought, and i decided to unoverclock my GPU to see if it fixes the problem. After i did so, i was able to play on worlds for a long time without the black screen occurring. the reason I don't say this is a complete solution is because the black screen did occur one time after a few minutes of opening up a new downloaded world. Besides that one time, I was able to play on a world with my friends for over 4 hours and no black screen occured, which was a new record for me. So, maybe you just have to put less stress on your GPU and the black screen will go away.
