Now running Nvidia 195.81 beta drivers and still getting this problem. It's affecting the icons on Bartender4 bars and also the icons on the config buttons on ArkInventory.
It went away for a week or so then came back. I still don't know what's causing it. It's either a 3.3 issue because it really only happened after 3.3, or it's some addon/library issue that handles icons in mods.
Granted a simple UI reload fixes it, but it's still a hassle to have to constantly do it.
