Mouse vertical movement inverted when running as HyperV guest

[stuclark75]

Since sometime in Janary (sorry, don't have better details as I don't update daily), mouse vertical movement has been inverted (up goes down etc.) when running Haiku as a virtual machine under HyperV (Windows 11 host).

This was previously an issue last year, but was "fixed" sometime in ~July, but has now regressed.

Did you try this? "Disable mouse integration: In Hyper-V Manager, select the virtual machine and go to the Settings. Under the Integration Services section, uncheck the "Mouse" option. This will disable the integration of the mouse between the host and the guest OS. Restart the virtual machine and check if the mouse movement is now correct."

I've tried all available integration options, including enabling and disabling all options. None of these settings makes any difference; neither does completely deleting the VM and recreating.

(mouse integration isn't available as a seperate option in HyperV under Win11, but "guest services" covers it)

I have the same problem. I also tried to turn of "Use enhanced session mode" in Hyper-V settings, but it did not help.

For me, inside Hyper-V VM under Windows 11 (tested with 24H2, but applies also to some builds before it), mouse is incorrectly detected as a trackpad. Other operating systems have special mouse "driver" that can flip Y-axis in settings.

Mouse works correctly as Hyper-V guest on earlier releases of Windows 11 and on Windows 10.
