Nameplate Flickering since patch 2.16

Time: Since the 2.16 Update
Frequency: Always
World name: Gilgamesh
Character name: O'Mytenia Artyl
NPC name: All of them
Monster name: All of them

Area and coordinates: Everywhere
Steps:

Since the patch,when using Crossfire in Afr mode,the Nameplate don't appear as normal

-the text cut and overlap either itself or someone else name in the field of vision.
-sometime the entity name itself is not there at all and is replaced by a cut-off part of someone else name.
-Any screenshot taken are all black


Disabling crossfire fix the issue minus ~40% performance
Setting crossfire in Optimise 1x1 fix the issue minus ~20% performance and cause severe flickering in cutscene.

Windows 7 Ultimate 64-bit
AMD Phenom(tm) II X6 1100T Processor (6 CPUs), ~3.8GHz

AMD Radeon HD 6950 (x2) w/13.12 driver

I can confirm this also - Crossfire'd cards in use. Similar specs to user above. Shouldn't have to disable Crossfire to play so hope a fix can be found soon.

(Tried updating drivers also, didn't work)
