Control card and hotkey graphical glitch.

Since the most recent patch of a day or two ago, I've been getting a strange UI glitch.
All my hotkey and Control card icons are blanked out, or covered over with solid colours. They all still work and the tooltips come up when I hover over then as normal, so it isn't affecting gameplay beyond making it a little harder to find the right crafting option.
It is worth noting that this glitch doesn't seem to apply while I am visiting Providence. While in town, all UI displays perfectly normal, but changes back to glitched when I teleport back to my home claim.

In addition, the framerate has tanked significantly and there are some texture striping issues with things like skins on a drying frame
Anyone have any suggestions?
