screen flicker issue is coming

Hi there, SNoorulain.

To confirm, you are seeing the screen flicker when only using a specific app?

If that is the case, then please try the steps below to see if that might help:

1. Quit the app by going to the menu bar > app name > Quit. Quitting and launching it again may help reset the app and app data, which can resolve issues.
2. Ensure that app is fully up-to-date by check for updates within the app or the App Store: How to manually update apps on your Apple device - Apple Support You'll want to ensure that the latest update is installed, as updates may contain fixes.
3. You could try restarting your Mac mini in the menu bar > Apple () > Restart. Restarting can seem like a simple step, but can refresh macOS, which can sometimes help resolve issues.

If this is happening with multiple apps or on multiple screens (like when starting up or shutting down your Mac mini), you may want to ensure that all the connections for your Mac mini are connected properly and not loose. Loose cables can sometimes cause flickering issues. This article has more details: If your Mac display doesn’t look right - Apple Support

Let us know if those steps help or if those have already been tried.

Take care!

Thanks for replying, SNoorulain, and that additional info, it really helps! You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.
