it doesn't crash so i don't have a log to report, the screen freezes, for some reason i can still move and perform actions but the problem is i keep seing the same image with some weird textures, chests bed and stuff spammed on my screen, the only solution is alt f4, it happened in multiplayer ONLY when i used the dragon staff on a royal red to give him diamond armor.

I have the exact same problem in single player, but in my case it is whenever I have it selected in my hotbar, although it only started after I gave a Royal Red Dragon armour. Makes the staff completely unusable.
