My MacBook is glitching since I did the update today. It keeps flashing other open programs while I’m working in another one. How do I fix that?
MacBook Pro 13″, macOS 10.15
Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

If still a problem reinstall the OS...
Start up from macOS Recovery
