blur on main menus occasionally causes game display to freeze permanently

When browsing through the main menus with blur enabled there is a chance a lag spike will accrue. This will freeze the display but still run the game normally in the background. This doesn't appear to happen when you're in a world, only in the main menus. The only way to fix this is to restart the game. 

Exiting and entering fullscreen bugs out the screen when frozen. 

Edit: It only seems to trigger when on fullscreen
