There is another thread that includes this issue, but because it also includes a bunch of people talking about unrelated stuff, I decided to make a new thread for this problem specifically.
I play on PC-NA, and the issue happens across all characters. I've contacted Customer Support, and they told me to post about it here.
I have a texture issue that affects a lot of things in the world, the worst affected are rocks, trees, and buildings (moss I think?). It makes them look black. I have also noticed it on the Bloodforged skin, specifically on my Argonian's face, where it has no texture and makes it look like he has no nose holes. I have also noticed that it affects the block indicator, the shield thing that floats in the air when you are blocking. It is very faint, almost invisible. I attached screenshots that show all of these issues.
The issue happens with and without addons. I have tried repairing the game twice, with and without addons, saved variables, etc in their respective folders, and also reinstalling the game, to no avail. I have obviously also tried relogging, restarting the game and my computer. I included a screenshot that shows the issue happening when there are no addons, taken directly after a game repair (look at the rocks in the background).
I have a screenshot from October 27th that doesn't have the issue, and I have one from November 4th that does, so it started happening to me sometime in that date range.
Any help with this issue would be appreciated, my Argonian can't breath through his mouth forever!
