Hardware: Asus RX580 4GB Dual fan series, connected to a Samsung Syncmaster BX2250 at 60fps, 1920x1080 on HDMI
CPU: Ryzen 5 1600
OS: Windows 10, version 1809 with all updates
Driver version: 18.12.2, all default options and yes on install
Observation: Monitor goes to sleep as normal under power settings. When monitor wakes up, screen is flickering several times per second.
Expected behaviour: Monitor should not flicker when it wakes up.
Temporary remedy: Going into Radeon Settings and toggling Virtual Super Resolution or GPU scaling stops the flickering.
What didn't work: Uninstalling Adrenalin 18.12.2 using DDU in safe mode and reinstalling it.
Help appreciated, much thanks!
