Lines on screen after angels attack or spell used

[unmerged(213178)]

Sometimes (Not all the time) when a unit like a seraph attacks or a spell is cast such as lightning i will get lines that come across the screen which stay there the whole time through out the battle. You can rotate around them like they are actually a line of polies. They also lag the game up alot.

Here is an image of it happening.
