Hello. My apologies. I've corrected the screenshot, the other had no issues. If you look at the door you'll see two white triangles. All doors in this area have that. I think the one wooden beam also shows it to the right of the doors. If you get closer, they go away.

If I turn off LOD this behavior does not happen. I experienced this exact issue ~ 2 years ago with a different PC & card. May be a graphical glitch with these doors that only appear when LOD is on.

Thanks.
