AMD Catalyst and Windows Store

Hmmm. It seems when I have AMD Dual-Graphics turned on, the Windows Store and other various parts of the operating system doesn't work. The store will just sit there for a few minutes with the swirling dots on the app properties screen and then crash.

Likewise, when varying things are called up, like Task Manager, Explorer, Command Prompt, etc. they have to be called up again because of a pop-up error that appears that says, "The stub received bad data."

If you have a system equipped with AMD Dual-Graphics, please turn off the dual-graphics capability when you're not using it.

I have dual graphics turned on and am not experiencing any issues.

It doesn't appear you've filled in your system specs yet. We're not sure what you've configured to make your Store work even with AMD Dual-Graphics/Crossfire turned on.

Another thing I found out is that when I turn on Dual-Graphics with the IGP set as the primary GPU, and the graphics card set parallel with one another, the window styles get messed up. Windows Store up at that point isn't affected, but, good luck looking for all of the buttons to close, or minimize the app windows with.
