 Also experiencing this with the new 2021 iPad mini on 1.17.30 

can also confirm on IPhone 12

Yes that appears to be the same problem.

Can Also confirm in 1.14.1

I’m also having this problem, and since the latest update my world has become somewhat unplayable,

Here’s a recording I made of a typical gameplay session on Switch

I'm still having this problem in 1.5.3 for windows 10

same here Error: Could not find or load main class net.minecraft.client.main.Main

tried the same skin on W10 bata 1.2.0.31 and it works fine

Confirmed in 1.11.2

Yes Roy Sajima, that was my problem ~facepalm

I was using the a repeat command block with "/scoreboard players set @e inGround 1 {inGround:1b}"

and a connected chain command block with "/scoreboard players set @e inGround 0 {inGround:0b}"

but the chain command block was set to "needs redstone" ...~facedesk.

sorry for wasting your time :/

That is not a bug, it's a feature, the top texture of grass and dirt blocks are flipped and rotated randomly to avoid unsightly tile repeating.

I believe the top of TNT blocks also do this.
