The entire game is generally glitchy. Every second or so, the screen will flash white or light blue. The chunks all load very slowly. The game lags a lot more than usual. Sometimes the edges of the screen will flash white or black. All the inventory tabs flash wildly and inconsistently. Especially the Foodstuffs and Search Items tabs. When the inventory is open, what looks to be pieces of blocks will flash all over the screen. It's hard to describe without seeing it yourself. But it seems like the enchanted books do it the most.

Also, sometimes the game will run just fine. The chunks will load quickly, there's nothing flashing, and it's not lagging. But the inventory stays an issue.
