Weird glitchy knitting-like pattern

I turned on my laptop one day and this just showed up. Any ideas what it could be? I've already sent it to MSI for warranty repairs so I just want to know what it could be.

It disappears when theres any movement on my screen (like say it'll stop showing when i move my cursor) and then it reappears. The white glitchy screen is just like that it doesnt move or anything. it doesnt show up on the bios screen thingy. It only happens when I swap to the integrated gpu mode on msi user centre.

But theres also like a weird jaggerdy lines when i swap to the discrete gpu which disappears when i change the refresh rate to anything. (I'll upload the image in the replies since i cant seem to post multiple pics)

I got this laptop 3 weeks ago and it hasnt had any physical damage or anything like that.
