MacOS Ventura Updated - MacBook Pro M1 Pro screen flickers now as my second monitor

I currently have my 14" MacBook Pro (M1 Pro) hooked up to an external monitor and I use the MacBook Pro's screen as my second monitor via a Thunderbolt 4 dock. However, after updating to MacOS Ventura, I noticed that MacBook Pro's screen starts to flicker intermittently. This never happened before and I was wondering if there was a fix for this?

MacBook Pro 14″, macOS 13.0

I tried upgrading to the Ventura 13.1 Release Candidate earlier today, no improvement at all, actually slightly worse than I have had the last few days with Ventura 13.0.1.


I sent in a new feedback to my existing ticket in the feedback application today with 13.1 RC installed, no response or any signs of activity from Apple's side since 26 October, also states zero similar reports.


I have just wiped the drive and reinstalled Monterey, and flickering is not any issue anymore. This happens exclusively with macOS Ventura.
