Also screen flickering when playing games which not support 144 Hz in 1440p. For example in Wolfenstein New Blood whic is only 60Hz.
Also it is terrible tearing when in-game video playing in Wolfenstein New Blood if I not switching FreeSync in my monitor settings.
If I play Battlefield V 144 Hz 1440p it is much better and it is without much tearing or flickening.
Sometimes it reducing FPS so I need fully to reintall drivers with DDU.
I hope this can be fixed with new drivers.
