Cant tell if it will work for you, but I experience simular problem.. (HD7970)
Solution for me, is to simply uninstall "AMD catalyst control center" thru settings/ system /apps &...

Spoke way too soon.. and now start "the area with the live tiles" is starting to act up too.. disappears after 1-2 seconds
something is just not right when logged on to ms account at all.. :huh:

Had same problem, seems like unchecking "allow web content" in AMD catalyst control center solved it for me.. will post back should problem reoccur.
