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)

If "Reduce transparency" is switched off everything is ok.

You will find it here:

System Preferences / Accessibility / Display / Reduce transparency

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.

How to test an issue in another user account on your Mac

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!
