Some Glitches

So... Update 1.10.0 is very good. Performance on switch is finally normal and stable. But... I got few things to report.

1: Shulker boxes full of items causing lags in inventory menu.

2: When i wanted to swim screen gets black and i cannot see anything. (This glitch isnt active all the time but sometimes)

3: Some horses are usseless becouse of its slowness.

4: I don't like new textures. This would be great to add Classic Textures for free to minestore.

5: Sorry for my bad english (I'm from Poland)
