Weird Texture Bugs on PC (specs and clips in description)

So I started seeing these kind of texture-glitches a few months back, here’s two clips of them:


Using an RX 580 with 8gb of VRAM and around 5.5 are in use during gameplay
16gb of ram
ryzen 5 2600 @4ghz
temperatures in the 50s to 60s during long gameplay sessions
anyone else having these Bugs in their game or an idea what might cause them?
this also only happens in PvE for some reason
