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

Same here mac pro m1 max 2022 (MacBookPro18,2). I have 2 4k monitors connect via laptop thunderbolt. It happens intermittently. It happens more often when the mouse comes close to the edges of the screen.

This also happens to me on my MacBook Pro M1 13-inch (2020) connected to a Gigabyte M27Q via USB-C. I can reproduce it with 100% consistency by doing the following:

Steps to reproduce:

1. Set external monitor as "Main Display"
2. Open any browser on the external monitor (Safari, Chrome, Firefox) and set to full screen.
3. Go to YouTube and play any video. Leave it playing in standard view.
4. (Important) On the MacBook display, open any application and set to full screen. I use Spotify.
5. Back on the external monitor, open Control Center (via Menu Bar) and enable/disable True Tone or Night Shift. Flickering won't occur if you do this on the MacBook display.
6. Observe flickering.

I'm almost certain that it's an issue with Ventura because flickering occurs with almost any browser and application combination, so long as you follow the steps listed above.

Following Pavan Kulkarni's line of thinking I was actually was able to fix my flickering.

On Ventura's "System Settings" then "Displays" selected the display that was flickering, and changed the Preset from Apple Display (P3-500 nits) to Pro Display XDR (P3-1600 nits). Has not flickered at all in the last while, before it was flickering a few times a minute.

Hope this helps somebody.

I got the same issue with my MacBook Pro 14" with M1 Pro chip, got a LG 27" 4K display directly connected to my device via USB-C, got intermittent flickering on the internal display, tried a clean reinstall of macOS Ventura to rule out potential upgrade issues.

The same is happening with my Macbook Air, M1 2020 since I updated to Ventura. I'm connected to a monitor using an Anker USB-C dock. As far as I can tell it only seems to happen with me whenever a video is playing on my second monitor (Youtube in Firefox), but I have only just updated to this version of MacOS so it may start happening in other instances too.

Apple fixes issue reported to them through Apple support that end in Bug Reports.

Unless/Until enough people make their cases, and work through obvious work-arounds (¿is the plug in the wall?) they are 'fat and happy'. Make them less complacent by reporting the issue and working through the flowcharts to get to a Bug Report.

I have the same issue.

I am using a MacBook Pro 16'' (M1 Pro), connected to 2 external monitors with a Thunderbolt 3 to 2 DP adapter.

External Monitors: Dell U2718Q and LG 27UL550W

It happens a few times per hour, seems very random to me, sometimes it just happens when I am not doing anything.

It usually happens a few times in a row, lasts for about 10 seconds. Desktop picture goes black and Dock disappear, and they comes back in a second.

It seems to be the Dock process keeps dying and relaunches. Looks exactly the same as if I run this command in terminal:

killall Dock

Are all of you connected to HDMI or Thunderbolt. It's happening to me as well on HDMI and as I typed this I did notice something that is fixing the problem. Try to switch off True Tone and check how it works. And mine's an Intel Mac 16 inch from 2019.

But apart from this, a lot of other display glitches like if I double tap for Mission Control, multiple windows flicker and overlap for a fraction of a second. Hope they fix all these soon, seems like driver issues.

I also expriencing same thing. Maybe there are bug happening on graphical processing, have you restart your macbook and try it again. I resolve the problem by doing that. Maybe Apple can recognize this problem and solve it on next ventura patch update

Since we had a update for Ventura yesterday, are anyone able to reproduce the flickering on 13.0.1? I had to downgrade to Monterey for the time being, due to the screen flickering increasingly getting worse.

I personally only have the issue when there's a video playing on the MBP monitor, then the external one flickers.

After updating to 13.0.1, same, I would even say worse after watching one video (only one though): the external display just went dark completely.

Stopping the video playback "resumed" the external monitor status.

Same for me. Happening on my Intel MacBook Pro 16-Inch, 2019 and Pro Display XDR, since Ventura update. Verified wasn't cord, MacBook ports, monitor, or power. Also, submitted bug report.

Doesn't happen when connected to my Studio Display.

I did a clean install of macOS Ventura 13.0.1 today, to try some of the tips of changing the colour profile on the built in display, and whether disabling True Tone would work, none of those have given my any better results, display is still flickering, and have even gotten worse since I tried Ventura a few weeks ago.

My display is a LG 27UL850-W, directly connected to my MBP 14" with the cable the monitor was shipped with, this works fine with no issues at all in macOS Monterey.

I would agree if this were general issues, however there have been no issues with any other devices I own, and it's completely specific to macOS Ventura. As soon as I run any other USB-C device, or macOS Monterey on the exact same device, there is no issues at all.

The original cable is completely fine.

Is anybody going to solve this issue with an update?

the issue started since I've updated my Mac Air M1 2020 to Ventura 13.0.1 and definitely not related to hardware issues.

I've tested it with different dock stations and different cables. Meanwhile this setup works perfectly fine for another machine without Ventura OS
