Hi guys. I am experiencing a problem with my screen after update to OS Catalina.
Suddenly, a line of pixels appeared above the menu bar and started to flash. This problem only happens when I log in into my profile because the pixels disappear in the Login screen.
Here is a video: https://youtu.be/0eWvKbUoj1c
Please, I don't know what else to do.
Thanks in advance,

Hello erikfromm,
Thank you for using Apple Support Communities! I understand from the information you provided that you have some flashing pixels that appear at the top of your Mac display; I'd like to help.
Do you have this same issue if you change the Desktop picture or background? Here's a resource that could help:
