Monitor is a Asus PG32UCDM.
When playing Youtube videos in full screen using the Brave browser, the monitor’s refresh wildly fluctuates. This behavior is observed through the monitors OSD. This results in occassional black screens and loss of signal with the monitor. After some hours of troubleshooting the issue, the culprit is the KDE-Plasma VRR “adaptive sync” setting being set to “automatic” or “always”. When set to “never”, the display does not experience this issue.
