--- Comment #2 from Nicholas Johnson (nicholas.johnson@outlook.com.au) --- Okay, tried with AMD R9 Nano inserted into a desktop PC with same config as laptop - one display on Intel GPU, FreeSync display on Radeon, except this time, it is in an internal PCIe slot (no Thunderbolt).

Same bug. Will attach new dmesg output. The line containing "Jun 5 09:12" is when I enabled FreeSync in the U32E850R monitor's menu.

So it has nothing to do with Thunderbolt external graphics. This is a bug for anybody with Radeon and FreeSync monitor.
