Xp bar doesn't update properly
Exemple : you're on level 0 , you kill bunch of mobs and get their XP
You'll stay on level 0
When you select something on the hot bar
A sword for example, you'll see that the XP updated and you're on a higher level

Beds disappear on a certain viewing angle,

Lots of lag

Weird lines appear on top of letters

Graphics bugs , weird lines appear on blocks , actually its parts of blocks behind the block you're seeing , Exemple : grass block behind oak wood planks, when you look at wood planks you'll see lines of grass blocks

I hope you understand

Fix asap
