Opaque buttons overlay on S5...What are they?

[Damiensrules]

I noticed 3 new barely visible buttons (pause, "Ex", and settings cog wheel) in the upper left corner which I can't press on my S5 home screen and cannot figure out what app that belong to. Worried this is malicious activity... Please help!

Also, I cannot take a screen shot because they are an overlay and not captured. They are constantly visible except when screen is off of course.

Re: Opaque buttons on home screen...What are they?

Had to take a picture of my phone with a co-worker's phone in order to see the overlay...not very clear as these are barely visible in person!

Confirmed the issue is Image Burn from an App...any suggestion as to how to fix this?
