Note on the flicker. Flicker happens anytime clocks change on the desktop. Any apps that requires gpu acceleration will induce a clock change. Apps like browsers, flash, media players, etc all can use gpu acceleration can do this. It is just something you have to acknowledge and understand.
Now the crux of the issue is Powerplay which is the AMD process that changes these clocks when it senses load. The problem is we want X clocks to run all the time on the desktop and for it not to start jumping into the various clocks settings which AMD calls powerstates. In official mode, you cannot control these powerstates so whatever Powerplay chooses you under its control. In unofficial mode you can choose to ignore Powerplay and set up your profiles how you see fit. There is a bug where sometimes AB cannot keep up with Powerplays clock switching and you will notice a flicker when watching something like youtube. In this case you can simply hit reset in AB and it will reload your 2D profile, and shortly after will drop your clocks back to idle.
For me, I'm ok with this bug cuz it doesn't bother me because I realize what's happening. It's not frightening or alarming when you know why. Watch the video and you will see AB and Powerplay fighting it out which should give you a better understanding.
