Not aligned screen

I understood the question— but the clarification helps what I a seeing here is a dirty screen border.

—Try changing the resolution of the screen

>System Preferences>Display and see if this makes a difference redrawing the screen

—Try changing to a hidden menu bar

from >System Preferences>General>Show/Hide Menu bar

Does anybody else have this problem on their MBP that the bar on top doesn’t align with the background? I’m guessing it’s a Catalina issue. it also suffers from the glitches on photos where the coloured checkered flags flash while scrolling.

Rebooting is always the first attempt.

I am not sure what I am seeing here—the menu bar is typically pegged to the top, here your photo shows it dropped down into the field?

Are you using a Virtual Machine?

What does this mean "it also suffers from the glitches on photos where the coloured checkered flags flash while scrolling."

To trouble shoot further you can:

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.

In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.
