I am using an Acer Aspire 7560G laptop with muxless AMD-AMD hybrid graphics, officially 6520G integrated and 6720G dedicated:
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek [Radeon HD 6520G] 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff)
This configuration causes kernel errors whenever the dedicated card gets touched (usually by either running lspci - which takes a while to run - or turning the monitor off and back on again). Visually that shows up as flickering and parts of the screen not refreshing properly.
If in the BIOS I turn off the dedicated card completely, I don't have this problem any more.
I tested it with kernel 4.7 and 4.1, both had the same results. I'm running openSUSE Leap 42.1.
Here's the relevant part of dmesg (full dmesg is attached):
