I have the flickering problem with 2560x1440 screens, AMD Radeon RX 550.
tried it on two screens: asus and samsung. asus is capable of freesync, samsung not. asus can handle higher frequency, samsung 50Hz only.

On samsung it works without any problems. On asus monitor I have the same flickering problem on 75Hz, switching down to 60Hz solves the problem.

I'm on Ubuntu 18.10, kernel 4.18.0-16. - with very intense flickering.
Upgraded to 5.0.2 kernel manually, seems like flickering is a little bit better.
