Flickering at the bottom of screen

Hello everyone. So for some time I’ve been having a bit of flickering at the bottom of the screen of my Herobook Pro. The moment I power it on, once it arrives at the log in screen, the bottom of the screen horizontally starts to flicker in a very distorted way. Weirdly enough though, when I restart the laptop, and it starts back up, the issue is gone. The moment I power it off and turn it back on, the issue presents itself again. Thank you in advance for any help.

Would you mind to post a video, so i could sent it toTech. I am not sure if may be hardware or software
And also the Serial number
