Blotchy Red Areas?

Posted a separate message about Scan & Repair failing, but the reason why I was trying thagt was because I frequently get red glowing area in my view… as I get close to them, they seem to “resolve” into proper textures. Also happens with some distant NPC/mobs… not all of them, just some of them. Have got indications I am NOT the only one seeing this. Asked some win users, they are not seeing this.
