So I've been getting these lens flare looking dots flashing on my screen here and there and I can't figure out what's causing them. They can be seen the most at the beginning and end of the video here.




Here is a pic of my video settings. Trees relief is also off.



Does anyone have any suggestions for what might be causing this or how I can get it fixed? Also, if I switch everything from medium to low, the colored dot things are replaced by semi-transparent grey boxes and rectangles that flash for the same amount of time.

I'm running an i5 4470 at 3.2 ghz, an AMD HD7870 2gig, and 8 gigs of ram. Nothing is overclocked, all temps are below the overheating range whenever I check them.
