The error happens on certain maps like rhun or lebennin. However this error occures only on operating systems: windows vista and later versions more specificly happens on laptops the most.
Whats the CAUSE:
I found a person who said the problem was the compatibility modus that was actually causing it in the first place.
What to DO:
Remove all compatibility settings in the shortcut properties.
