What happens

Textures switches between mip ones and normal on hw renderer depending on the camera angle. It doesn't depend on player's distance from object.

What should happen

Textures shouldn't do that. As they didn't do that on sw and v1.16.6 and earlier on hw.

This doesn't look good hm.

Right, we merged the 1.16.6 hotfix branch into 1.16.5 at -222, resulting in 1.16.6 numbering from there on. But presumably, there was some commit between 1.16.5-1 and 1.16.5-220 where it also started to happen, would be useful to know which one.

The dump seems to render fine on PC:

But I'll look into it soon. Looks more like a UV scale confusion than mip levels shifting..

I didn't tried to load frame dump, cuz I didn't know how to. But now I know and I've tried. For some reason it dosen't shows when you load a frame dump.

I've found that place where it reproduces easily now. I'll track it down.

Found the problem, but I've got a couple of options for the fix. Anyway, there will be a fix soon.
