Linux host, Windows guest: screen resolutions limited and fix messes up the pointer

[JN]

1) Windows 10 VM exposes only resolutions lower than my native one. I worked around the problem by issuing this command:

VBoxManage setextradata global GUI/MaxGuestResolution any

However - and this is problem 2) - once the VM was using my native resolution, setting the scaling within my Windows 10 Guest to 150%, and especially to anything higher, causes pointer strangeness in Word 365. For, once the pointer changes - changes upon mouse-over of an icon in the Word ribbon - it does not, for some time or occasionally permanently, change back.

An existing bug report contains the first of the two problems that I have detailed; however, I am afraid that I cannot manage to re-locate that report.

1. Windows will not present you with your host's full resolution, because it can never get it. You have to take into account the status/menu bars, window frames, etc. The only way to get the full resolution, is to go full screen. Then you'll get it. That's not a "bug", that's reality.

2. This 150% scaling and higher causing weird mouse pointers sounds awfully similar to ticket #17778. Take a look at it, along with the linked posts in the forums.

3. You were supposed to follow these steps when you filed the bug, and provide a VBox.log:

   Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.
