My MacBook Pro's screen flickers, but not ordinarily. What do I do?

I have a 2019 MacBook Pro 13 in. Quad Core model. There is a small segment of my screen that slightly flickers in shade, constantly, but only on my desktop. I don't see it when I have any other application full screen, or when I'm signing in. Doesn't that rule out any hardware issues? I reset my RAM and my SMC, still have it. I created a test user and the user didn't have the issue. In safe mode, the flickering is nowhere to be seen. What can I do? 

MacBook Pro 13”, macOS 10.15

Reinstall macOS.


Reinstall El Capitan or Later Without Erasing Drive


Please be sure you back up, if possible.


  1. Restart the computer. Immediately, at or before the chime, hold down the Command and R keys until the Apple logo and progress bar appear. Wait until the Utility Menu appears.
  2. Select Disk Utility and click on the Continue button.
  3. Select the indented (usually, Macintosh HD) volume entry from the side list.
  4. Click on the First Aid button in Disk Utility's toolbar. Wait until the Done button activates, then click on it.
  5. Quit Disk Utility and return to the Utility Menu.
  6. Select Install OS X and click on the Continue button.


If this doesn't fix the problem, then do this:


Install El Capitan or Later from Scratch


If possible, back up your files.
