Flickering/glitching on the Screen

My MacBook Pro(version 10.15.7 from 2017) has black lines of flickering near the menu bar that will slowly drag/fill the top of my screen if I let it be. Therefore, when it gets bad or a lot of flickering, I will let it sit for a while and it will be gone. This has been going on for about three weeks, and it is getting worse. In the beginning, the flickering only happens after 3-4 hours, but now it happens even after 30 minutes or so of use. Is this a software or hardware problem? Screen problem? What can I do?

MacBook Pro 13″, macOS 10.15

Please check in safe mode if you have same issue. (Please go through the support article)

How to use safe mode on your Mac - Apple Support

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
