Couldn’t find this on google or by searching the forums, so I thought I’d post here.
Here’s a screenshot: http://i.imgur.com/44q6Vp4.jpg
As you can see there are random weird color things on the bottom. This occurs either the first time I load into a map and persists in every game thereafter, or sometimes appears randomly in the middle of a game. It doesn’t appear on the menu, only while actually in a game. Once it starts it doesn’t go away until I restart the game. I’d say it probably happens in about 1/6 of my play sessions.
My specs:
Windows 7 64-bit
AMD Radeon R9 380
AMD FX-8370E
12GB RAM
This also happened on a different hardware build before I upgraded, which was also running an AMD GPU and CPU.
