Hi Chris,
1) There is an issue I faced with newer versions of proxmox as well. I had to follow this advice:
To quote here directly:
> I had something similar happen to me. To
fix it, on the affected VM I unchecked the 'Use tablet for pointer',
then re-checked it. This seems to have fixed the issue for me.
This setting is under "Options" when you click (or double-click) into your VM.
2) If the resolution is not syncing, make sure "spice guest tools" is installed by downloading the latest one from
https://www.spice-space.org/download.html. To troubleshoot, you can also try setting a Custom Resolution from the settings of the app.
Let us know how it goes!
Thanks!
