This black background keeps popping up behind my crosshair and it is really annoying. The textures also look grainy, and I have tried the following to solve it, but nothings works so far. :
 
I have tried restarting minecraft, and my pc. I also took off all my textures and put them back on. I also spent time looking up solutions if anybody had the same problem. So far, no solutions found. This seems to be a glitch with the new update because it only started after I updated minecraft. Please reply immediately if you have any solutions that I have not tried. Thank you for your time.
