Rebuke Screen Scamble!

The rebuke is one of my most favorite weapons, however… When ever I use it the graphics scramble and quite often I need to FORCE QUITE the game and reload it! if it does not require a quite the graphics are so scrambled that the men look like spiky Easter eggs! The screen will wash out and change colours, or it just goes pure white, black or orange? I get they want the effects of this weapon to be pretty but this is just crap! Lets just use the normal effects that works perfectly and does not interfere with the functioning of the game but they insist on having the screen shake and flash and then that just screws up the system! SERIOUSLY fix this please it is just a time wasting experience!
