Weird shadows

[NetSysFire]

There are some problems with shadows I am experiencing. These two videos might be two seperate issues but oh well.

borked.shadows.mp4

shadows.mp4

I would classify the severity of both as not critical but mildly annoying. As far as I can tell this is not a regression, at least not a recent one because it also happened when I started playing a year or so ago.

Steps to reproduce: Just walk around. You will spot the weirdness soon, but this appears to happen more often on those rocks.
