Macbook Pro Mid 2017 Sierra pink screen when wake up

Hello

I have Macbook pro Mid 2017 with touch bar 5 month old. 3.1GHz dual-core 7th-generation Intel Core i5 processor , 8GB 2133MHz LPDDR3 memory , 256GB SSD storage , Intel Iris Plus Graphics 650

Using Sierra 11.3.1 , when I wake up the mac from sleep the screen is stuck on pink screen for 1-3 seconds like in the following pic.. Apple support team has no idea what is it and the engineering team has no idea as well.. I saw that a lot of people posted the same thing in different variations.

Does anyone know whats the reason for it? any ideas?
