Weird Bug

This is a weird bug which does weird stuff on my screen http://imageshack.com/a/img839/8256/sm1k.jpg

Lol wtf, you probably have the water overlay on your screen. Hold Q then look at the post processing effects. Make sure they are all off.

It fixed that, but but I hear something like a heartbeat in the background. Probably a new addon I installed.Thanks for the help
