MacBook Pro M3 - Vertical & Horizontal Lines on Screen

I have been on the Apple ecosystem for many years, and this is my first time experiencing disappointment with a year old purchased MacBook Pro 3. I am very careful with all of my devices all throughout. Last night, flickering vertical lines suddenly appeared on my screen, along with horizontal lines at the bottom. This issue is very disappointing.

Could you please advise what may have caused this and how it can be fixed? I am currently based overseas, and I don’t think I will be able to make use of the warranty.

we are not apple

these forums are user helping other users like yourself, it's sort of going

to a physical apple store and asking other customers there advice

to me it sounds like a hardware malfunction, this can happen from day 1 of a product and it can happen after 10 years or more, the main reason for hardware warrenties is to help consumers if it happens sooner rather than later

Legal - Hardware Warranties - Apple

and maybe also

Warranty - Wikipedia

you can give them feedback Product Feedback - Apple
