I have XFX Fatboy RX590 graphics card - system less than a month old.
Everything was fine until 18.12.2 update
During games there are flickering, and on the desktop and other documents the fonts get distorted / flicker - see photos.
When the graphics card is disabled then the fonts are fine (with Windows card). Re-installed RX590 and all drivers, problem persists.
Any ideas?
