I've also experienced this and the Quonset hut being hard to fit through.

Just saw this in-game.

I can confirm that I haven't found any items in any of these houses, to the point that I rarely check them anymore.

Windwos 10 user reporting in, I've got the same issue and several more screenshots. Color changes depending on TOD and Weather. I've seen a few trees with this problem but in the distance, walking closer the texture pops back in.

I was on a server when it crashed, and it re spawned me as a fresh-spawn (Berezino), but in a different location than the first spawn (Chernogorsk). Logging out normally preserves your character.

I've experienced similar "jitters." I don't notice it too much when running around outside - although it does feel a little choppy - but when I walk in buildings its almost like I'm desyncing constantly.
