Scaled resolution cause display bug during shut...

Hello there, I've got problem with my

mid 2015 MacbookPro (Intel Iris 5200) 16gb ram

macOS Sierra

Problem:

If I set resolution to Scaled - anything higher than DEFAULT it will cause graphical bug during shutdown - patter looking like checkerboard/ louver on wallpaper. It happens only on resolutions (MORE SPACE) marked in blue rectangle on picture above.

Recorded problem:

(It's low quality but you can see clearly what's going on)

I've had motherboard already replaced in my mac, that is absolutely unimaginable how much I did struggle with few kernels every day, so I was happy that after motherboard replacement main problem was fixed (flickering, distortions, visual bugs and kernel panics) although I'm worried this 'small glitch/bug' that didn't disappear can develop into something that will cause serious problems in future...

I'm not sure if it is only my mac or there are other with similar problem, I don't know any other mac people and friends laugh of my and my mac problems (ty apple) is it hardware/ software issue?

If it is only my mac I'm bit worried and suspicious about repair of my mac because I've been told that motherboard was replaced - not fixed and I doubt that exactly the same problem would develop untill next shutdown when they shipped my mac back in may (I think) You may ask why I wait so long to go to some service station etc... so it was in repair almost a month and I didn't see this bug because default resolution was OK for me. I've got 3 moths left of distributor warranty and I'm not sure if they will fix it for free after all this mess with my mac :/

Anyone experienced similar problem? Any advices what should I do? I would install Yosemite but I can't download it. (If I remember well this problem was ' independent' of system but I could try it out)
