Seems that the Y-Axis (up/down) becomes inaccurate in Spice console when aspect ratio for VM desktop is not 4:3.

Using Virt-Viewer on Windows 10 or Ubuntu to control VM has this issue. Easily reproduced on VM using Gnome with Debian 11 or Ubuntu 22.04 with the default sidebar. Make VM Desktop Settings something that is 16:9 or 16:10 (not 4:3) and begin moving the mouse up and down the sidebar/dock. Soon the mouse can be over or under an icon by almost 50% and still affecting (focused on) icons it is not hovering over.

Guest additions (qemu-guest-agent) are installed from stable repos on the VM.

Anyone else see this or fixed this?
 
did you also install the spice enhancements? e.g. on debian they're called 'spice-vdagent'
also can you post your vm config ?

Thank you so much for pointing that out. I did not have 'spice-vdagent' installed and have now done so. Seems the glitch has gone away! That might be something good to add to the Spice help documentation / best practices. For completeness, here is my VM config.

yeah possibly, the problem is that the package might exist or not or have a different name for different distros/versions
but mentioning that installing some spice enhancing package might be good

EDIT:
actually it's already mentioned on https://pve.proxmox.com/wiki/SPICE under troubleshooting...
