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.
