SUMMARY My VRR/FreeSync 144hz monitor starts very subtly flickering after a game has been in fullscreen once, even after the game is closed. This only happens with my secondary 60hz monitor connected, it stops when the monitor is disabled or unplugged. Disabling VRR in system settings doesn't stop it, I have to completely disable VRR in the monitor's settings. STEPS TO REPRODUCE 1. Set VRR to Automatic in system settings 2. Launch any game and set it to fullscreen 3.
