Missing inner resize of Hyper-V Machine connected via VMConnect.exe in enhanced mode

[Huseriato]

Environment

Windows build number: Version 10.0.18363.900
PowerToys version: 0.18.2
PowerToy module for which you are reporting the bug (if applicable): FancyZones

Steps to reproduce

You need a Hyper-V Machine running Windows 10 (same build number as mentioned above) and connect via VMConnect in enhanced mode.

Expected behavior

FancyZones should resize the resolution of the guest operationg system (as it would to, when manually resizing the VMConnect window). May be there is an event missing, that must be send to the target window?

Actual behavior

When resizing the window via PowerToys Fancy Zones the guest is not resized properly (the VMConnect window itself will be resized). Manual resize of the VMConnect window resizes the gust operating system properly.

Hi @Huseriato
thank you for reporting the issue, this may be something depending on the way the VMConnect window processes the resize event. We will have to investigate if FZ can somehow trigger the internal resize of the window.

@Huseriato
is this still happening with 0.23? https://github.com/microsoft/PowerToys/releases/download/v0.23.0/PowerToysSetup-0.23.0-x64.exe

I will test this in monday and report you the current behaviour.

This is also still happening. I tested both bugs reported by me in the same go.

@enricogior, would like it if we could prioritize this for either .27 or .29. Going to assign to .29

@crutkas
we may try to send a window resize event to the application to force it to redraw itself.

[enricogior]

Different issue, but the root cause may be the same #5673

[enricogior]

I have tried several workarounds but none worked.
We might not be able to fix it. I also noticed that Windows Snap is also not working, it doesn't even move the window.

@crutkas
can you escalate this to the Hyper-V team?

[Huseriato]

I'm wondering about this. GridMove can handle this correctly. It's a project that's not maintained for several years and has none of this resizing issues. May be you can find the magic there?

[enricogior]

@Huseriato
did you get GridMove to work for you? I tried it and it works for regular windows, but it didn't move the VM for me.
I also tried to use the same API used by AutoHotkey to resize a window, and it resized the external frame but not the content.

EDIT: I got GridMove to resize the window but it has the same problem I just described:

@crutkas
this is not something we can fix, can you escalate it to the Hyper-V team?

@enricogior reached out to one person with you on the CC
