Mac OS Mojave vertical Dotted lines on native apple software windows

Hi everyone,

I downloaded the new MacOSMojave and I seem to be having some issues with dotted lines that appear in Apple apps/ software such as iMessage - Apple Mail - and Finder. These dotted lines appear after scrolling on those apps. Attached is a picture to show what happens. I have done Safe Mode and Reboots and _cmd alt P R_ ... Nothing seems to be helping out. Does someone have an Idea? Thanks!

MacBook Pro, macOS Mojave (10.14)

Good morning, Al505!

Welcome to the Apple Support Communities and thanks for asking about seeing a visual anomaly after scrolling in Apple apps. I can definitely see how that would be irritating and confusing. I'm happy to help.

My first recommendation would be to test in a new user.

If you still see the visual issue in a test user, reinstall macOS.

Please let us know if you're still seeing this issue after reinstalling macOS.

Have a great day!
