Benq PD2725u monitor was causing flickering/interlacing artifacts on MacBook Air M1. Suggested fix from Benq support.
What you can try against the error that you experience is the following:
- Go to the Apple menu > System Preferences.
- Select "Displays"
- Select the "Night Shift" tab
- Turn off the "Schedule" option by selecting "Off" from the drop-down menu and unchecking "Manual: Turn on until tomorrow".
- Wait for 20-30 minutes until the flicker disappears.
