I have a severe Minecraft bug that happens on the most random moment possible and it is very rare and it is an error of 1.15.2 where when you launch Minecraft on 1.15.2 after loading you try to click something in the main menu it does pretty much nothing and does not detect the cursor at all also if you try to put it on full screen the mc screen does not resize and end up making 3/4 of you screen black and after finding this when you close the game the games seems to be closed but it didn't even close at all because after I closed it, it was using the same amount of resources as it was opened meaning that the game sound will still be audible even with the game closed in a visual standpoint.

I tried to fix it by deleting the .minecraft folder to fix it but it did nothing to fix this bug
