bug when doing arena levels

[ronald.potter]

i have been having a ongoing prolem with the areana levels, in that i will get so far then the screen will bug out flickering all over the place and not allowing you to see where you are. you will be able to compete to enemies on the screen at the time of the problem, but then wont spawn anymore just leaving your character on the screen. while it still flickers.

it dosen't mater whitch arena challenge it is and can vary between waves as well.

as anybody else had this problem and if so what did you do.
