Glitch on my display since Sierra Upgrade

Hi! Im using Macbook Pro Retina, 13, early 2015. Everything was okay since I bought my macbook. After I have upgraded to Sierra, I get this weird glitch that only happen when I wake my macbook after 5-10 minutes display off/sleep.

After 3-5 seconds, the display went back to normal. Any of you guys encounter this glitch? Is this glitch because of software or hardware?

MacBook Pro (Retina, 13-inch,Early 2015), macOS Sierra (10.12.1)

Hello afiqsamat,
Thank you for using Apple Support Communities.

I understand from your post that after updating to macOS Sierra on your MacBook Pro you get an abnormal screen when waking it up that lasts for 3-5 seconds. I know how important it is for your MacBook Pro to wake up properly for you. The first step I recommend is to reset the NVRAM.
