I this something I should be worried about?

Even though this only happens when I use a third party launcher I think the phones speakers are responsible. Today I noticed a little flickering green bar at the bottom as well. Does anyone else have a similar problem?

I would say to just not use that launcher (or is it ALL 3rd party launchers, it wasn't quite clear?) What exactly is the screen shot showing us? Looks to me like just a black screen.

If you look at the top and bottom of the picture you see a little discoloration. It has happened with Nova Launcher, Smart Launcher, APEX Launcher, Next Launcher, and other Launchers.
