Another thing is that the Target Frame sometimes gets stuck when I deselect someone and all that's left out is 2 transparent(80%~) bars which happen to be hp/mana bars, text gets also removed as well. De-selecting/targeting a couple of times usually solves the problem.
I'm having the same problem. This is what it looks like with no target and with a target selected. It makes it very confusing. It happens all the time and I have to zone or /reload to fix it.
