Hello doc_hira,
To start off, we advise that you restart your Mac (Shut down or restart your Mac) and make sure it's fully updated (Update macOS on Mac). Once those are done, please test this issue.
If the issue persists, continue by testing to see when this behavior occurs. First, put your Mac into safe mode and test. Booting into safe mode will disable any startup and login items from automatically opening, which can help us to isolate the source of the issue further. When you do this, you’ll see some unusual behavior from the display; this is to be expected. Please follow the steps in this article: How to use safe mode on your Mac.
If you do see the lines in safe mode (and once updated and restarted), further assistance may be needed. We want to make sure you reach the right team for help with your Mac, so we recommend that you contact Apple Support directly. Depending on your region, you may be able to reach them here: Get Support.
Thank you for participating in the Apple Support Communities and have a wonderful day.
