Distored resizing window resolution in OS X Guest

[TECH198]

In Fusion 10.1.2, when resizing guest OS X running Sierra, there's an odd resizing of the window in one direction, then back again.

Almost like its trying to resize to display smaller icon, but Fusion Preferences are  prevailing or something,

In Fusion 10.x, it supports HiDPI in macOS guest. After VMtools installed, the "Use Full resolution for Retina display" will be enabled in Settings -> Display.

It makes the UI in the macOS guest  as clear as that in the host.

When resizing window, it will change the resolution of the guest with full pixels first. That is why you see the smaller UI elements flash across. After that, it applies the HiDPI support in guest, the UI goes to the normal size.

You can uncheck the "Use full resolution for Retina display" to confirm it.

Sometimes this also appends in Fusion 10.1.2:

Workaround is to uncheck "Use full screen for Retina Display", then re-check it. So, it looks like HiDPI is not always working.
