Weird Screen Show up when Shut down

"I have the same problem with my Macbook Screen after display replacement. I took my MBP to Apple authorizes nears my home now and let’s see what happens!

Update (06/25/2020)

The Apple authorizer told me it is not because of hardware, it is software issue. I talk with Apple Support advisor USA, he confirmed it is Catalina 10.15.5 bugs and he asked me to wait for the next Catalina updates and We still can use our MBP as usual."

Hey. I ve bought my mbair in mar-20. The same issue persists from the day one. Its not a hardware problem, its an OS issue and Apple has been well informed about it. I was also worried and confused whether to change or not. But except this distorted colour appear for a nano second issue my mbair is running smooth. It occurs only during shutdown.

"Yes, you have a defective part! Time to get it fixed at a real Apple Store if you can. This is not a software issue.

The issue is the T-CON board which is part of the display assembly."

"So I had this problem last April til around June. I noticed this problem appeared right after I upgraded from Mojave to Catalina.

Since I tried all the Apple Hardware resets, I opted to downgrade my OS to Mojave again. Since a lot are saying it’s a Catalina Bug problem.

I went back to Mojave last June…and so far (Thank you, Lord) the problem’s gone. :)"

I have bought a mac book pro 2020 and i download Big Sur. When i shut down the laptop i have the same problem of the colores in the screen. I dont know what to do. I wen to the store and the tell me that is a problem of the software and i have to wait until they upgrade the version. But i dont know if is better to change my laptop with the guarantee that i have. Maybe the problem is going to bee in all laptops because is a software. What do u recommend me?
