Screen Flickering, black and purple screen with Ventura 13.3

Hi AgedVagabond,

Thank you for participating in the Apple Support Communities. We understand you're having issues with your MacBook Pro display. This article has some steps that may help: If your Mac display doesn’t look right.

"If the image on your Mac display doesn’t look right, try one or more of these suggestions.

• If the display is black or dim: Try adjusting your display’s brightness.
• 
  
• If images are too large or too small: Try adjusting your display’s resolution.
• If the colors don’t look right: Try using the display profile designed for your display. For example, if you’re using a Thunderbolt display, choose Apple menu  > System Settings, then click Displays  in the sidebar. (You may need to scroll down.) Click the pop-up menu next to “Color profile” on the right, then choose Thunderbolt Display. If that doesn’t work, try calibrating the display.
• If your display is blurry: Make sure your Mac has detected that display. Choose Apple menu > System Settings, then click Displays.
• To see the Detect Displays button, press the Option key. Then click the button to detect the display.
• If the display is flickering: Make sure your Mac and display are connected to one another with good quality cables and adapters. You may also be experiencing interference from a nearby power line, a fluorescent light, a radio, a microwave oven, another computer, or another electrical device. Try relocating nearby electrical devices, or moving your Mac and display.
• If you see bright or dark spots on a flat-panel or Mac laptop screen: Your display may have pixel anomalies. If you suspect your Apple display contains a high number of anomalies, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device. 
• If none of these solutions work: If you have an Apple display and can’t correct the problem, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device."

It does look and sound like the issue could be hardware related. You may consider running Apple Diagnostics. Here's how if needed: Use Apple Diagnostics to test your Mac.

If the issue persists, Contact Apple Support to have a technician properly evaluate the issue.

Take care.

Stage Manager is definitely the link here.

I get flickering, only on the the launch bar icons at the bottom of the screen (not the whole screen) when moving left and right and ONLY if there are more than 7 or 8 windows pinned in Stage Manager.

Very strange..

Short Term tip, reduce the number of open windows until a patch is released, It is super annoying the flickering so worth it for me..

M2 MBP, Ventura 13.3

Hello There, I'm facing this issue too with my M2 PRO MP PRO 14" ... First I noticed it when I opened Apple TV with stage manager on. however when i close ether one or both of them the bug just disappears. I'm still confused if it's screen or software issue also I don't have any nearby apple store unless I take a 3 hours flight. Please keep me updated if you like.

I am having this issue also. Same setup as you (2023 M2 MacBook Pro 14Gb running Ventura 13.3.1). This only happens to me when I have a Google Chrome window with a pinned tab (and only the pinned tab) running and then switch focus from Chrome to any other application in Stage Manager.

Same issue here. I have a new MBP 16" running 13.3.1 also. I notice it only occurs with Stage Manger only when Apple TV is open and in Stage Manager. The flickering only starts when I open Apple TV and place it in Stage Manger and stops when I close Apple TV. It does not happen with any other app, including other video playing in Safari. I have yet to contact Apple Support. Any word?

same exact issue after updating to ventura no issues, only happened when using tv app for first time as well as using stage manager & TV app is running in the background

possibly some rendering quirk with TV app? Digital RIghts management?

Did you mean, you only use apps you know don´t cause problems?

Just checking :)

I think it’s a stage manager related issue! Try to turn it off and check if the issue still exists?

Same problem here, stage manager.

Reinstall does not work, tried twice.

If apple is reading, are you guys planning a patch?

Cheers,

I HAVE THE SAME EXACT ISSUE!!! Only with apple tv.. otherwise the screen is perfect.

Could you please contact me via twitter to cross check?
