How to fix macOS Sierra 10.12 screen blinking on VirtualBox?

Question

virtual box

There is an MSI laptop, i7-8750H 6/12 threads, gtx 1060 on board as a discrete, UHD630 as integrated.
After installation according to the macOS manuals on virtualbox, friezes and image artifacts are observed, especially when scrolling pages in the browser.
Video memory artificially twisted to 256MB. Did not help.
Is there any guest additions for this mac? Or some alternative +- modern distributions?
It all comes down to cross-browser testing on safari 10+, so alternative answers are welcome.

Answer 1

Found the answer experimentally.
Use macOS Mojave + VMWare version. Sierra will not work properly with guest additions and therefore fullscreen.
Everything works many times faster, there is no blinking, fullscreen gets up automatically after installing the guest ones.

Answer 2
