For the past week I kept having these white lines that look like they're part of the frames of objects in the game popping up whenever I get close to a tree trunk and sometimes when I'm walking and look down at the ground. It only happens on one character for some reason and I think it was caused by a mod but I uninstalled the game a long with all my mods and it still kept happening. I had some clothing mods as well but the bug still persisted after I uneuipped my character and uninstalled the game.

It doesn't cause any crashes but it is very annoying and quite the immersion breaker. Does anyone know how to fix the problem?
Thanks.
