Macbook Pro 2018 Fuzzy Screen

[TypicalKorean]

Hello,
Last year on December I bought the Macbook Pro 2018 model with the touchbar. However I had encountered multiple problems with the OS. Now however, I turned on my Macbook but encountered a fuzzy screen. I immediately restarted my laptop, and the login screen popped up as usual. Still worried about the state of my mac, I restarted once again but into recovery mode, and ran first aid. I did not run diagnostics yet, and have contacted apple support via phone call and they have told me that it was either a simple error in my OS, for I do not completely shut off my mac, but I just put it to sleep. On the other hand they told me it might be an error in the OS and I might have to take it to and IT shop for AS.
Can somebody help me?

Thanks

You'll need apple or an authorized site to fix it. It looks like the GPU may have went from that picture.

Are you sure? I'm running diagnostics now, and If they all turn positive(no problems), should I just leave it and continue to use it?

Finished running diagnostics on my Mac(Holding D from restarting) and it says that there are no problems. Could this just be a simple malfunction?

If you don't need the data, reset SMC, NVRAM, then reinstall macOS (I typically format the drive at the recovery before installing). If the problem is there, take it to Apple.

But there seems to be no problems, do I have to reinstall? Can't I just keep using my Mac as normal
