UI: No text (name & remaining time) when hovering icons

[Nagoya]

I'm not sure if this is a bug, and most probably not so I'm sorry.

When I hover my mouse over a spell icon, or a buff icon, i get no text popping up with the name of the spell or the buff, nor do i have the remaining time on that buff.

I tried reloading the UI, but it didn't change anything.

Can someone help me? [You must be logged in to view images. Log in or Register.]
