Cursor Hover over items in inventory broken

[Mazzoff]

While i was playing all of a sudden hovering my cursor over items in my inventory and over my buffs did not display the popup identifying what i was hovering over anymore.

I tried logging out to desktop and that did not work. I was then recommended to re patch the latest patch on the forums.. this also did nothing. I'm stuck here with no idea what to do. Any help would be appreciated.
