Minimap blank/black

[Joie]

Was wondering if there is a known problem with the minimap being black? It shows the coordinates but the rest is just black.

Also on the 3D characters on self and target there is a icon on it in the shape of a speaker or volume control looking icon and it very often obstructs the showing of the lvl of my target. Is there any way to get rid of it?

Thx in advance for any help
