Hello and sorry for the delay. Im still getting used to the new AMD community forums.
There aren't any known issues with APU's and windows 10 that i am aware of. maybe amdmatt knows more?
Please make sure you have the newest AMD windows 10 drivers (15.7) and have them installed correctly.
Tutorial for proper driver installation.
1-Load windows with only your primary graphics card plugged in.
2-Disable any and ALL anti-virus/malware protection.
3-Download and Run the 15.7 (or latest) drivers from AMD.com (Omega drivers do not have Uninstall built in, you have to do it through add/remove, which is okay)
4-Choose to Uninstall/express (may not be available in newest version, download an older version) the existing drivers, and AMD folder
5-Restart the computer.
6-Disable any and ALL anti-virus/malware protection.
7-Run the 15.7 drivers from AMD.com
8-Choose to Install/Express the drivers
9-Restart. Confirm settings are working in windows.
10-Shutdown and add 2nd/3rd cards for Xfire.
11-Respond to this ticket if you have any further questions
** If you have nvidia drivers on your computer, you might need to run the Uninstall feature of Nvidias driver as well.
Please let us know,

I have the drivers installed as you discribed.
So far no good.
I have the same issue since I have upgraded from Windows 8.1 to Windows 10.
Symptom: all modern UI apps have an empty window title bar. Window name is missing, just like minimize, maximize and close buttons. They are there, but not painted, so I can close windows if I click the right corner of the title bar.
Closing and restarting dwm.exe will repaint every window that is already open and the missing elements appear, but any subsequent repaint event will hide those again.
If I disable dual graphics in Catalyst Control Center, then the issue is totally gone.
Tested with the following driver versions:
Windows 10 64-bit
AMD Radeon HD 7660D + HD 6670 Dual Graphics
