Several times lately when I'm using a browser, my screen sort of cuts in half as if a new email window is trying to open up next to the browser. It just flashes in there for a second, goes away and does that several times in a row. I tried restarting my 2022 MacBook Air M2 but it still has the "flashing" problem.
MacBook Air, macOS 13.4
Hey lat_lat,
Welcome to Apple Support Communities. The information below may help.
When this happens, have you clicked on a link in the web browser? If so, the link that was clicked may be opening the Mail app.
If that is not the case, make sure the macOS is up-to-date. Keeping your device up-to-date ensures bug fixes are installed. To check for updates, follow the steps below.
To check for new software, open Software Update. It's in System Settings (or System Preferences), which you can open from the Apple menu in the corner of your screen:
* Choose Apple menu > System Settings. Click General on the left side of the System Settings window, then click Software Update on the right.
* Or choose Apple menu > System Preferences, then click Software Update.
If Software Update finds new software, click the button to install it. You will be asked to enter your administrator password. During installation, your Mac might show a progress bar or blank screen several times, and you should avoid putting it to sleep or closing its lid.
If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only software that is compatible with your Mac.
For future reference, the steps are also available here: Update macOS on Mac.
If updating doesn't help, test in safe mode. Safe mode helps determine if the issue is called by an app that loads when the Mac boots up. This article provides the steps to boot into safe mode, and steps to take if issue continues in safe mode, and if the issue doesn't continue in safe mode: Use safe mode on your Mac.
Take care.
