--- Comment #27 from Yves W. <yves.weber at yahoo.de> ---
Same for me. flickering problems @144hz,120hz and even 100hz when using newer
kernel (tested 4.8.0 ubuntu kernel) or amdgpu-pro 16.30.3-315407 driver with
any kernel


- with default driver and default kernel (Linux Mint 18 -> 4.4.0-38-generi)
it's working at 2560x1440 @144hz, no flickering issues.

-> tried using the Ubuntu 4.8.0 kernel -> flickering at 2560x1440 @144hz,120
and 100hz. only 60hz works without flickering
-> with the amdgpu-pro 16.30.3-315407 driver from amd site, it's always
flickering at 2560x1440 @144hz,120 and 100hz. only 60hz works without
flickering
