[2022] Weird flickering behavour - random polygons around ships and SRVs

o7 CMDRs, does anyone else observe a weird graphics behaviour where random polygons are drawn all over the screen when in a ship or vehicle, and around ships/vehicles when viewed from outside (on foot / from external camera)?

I've reported a bug at FDEV, but I'm not sure if it's really one, or an issue with my GFX card. No other 3D application / game on the system shows this behaviour.

Could this have to do with Odyssey Update 12? I installed the update yesterday and played about an hour without the issue appearing; it only started appearing today.
