NoVNC guest mouse gone when upgrade pve-qemu-kvm:amd64 .

Hello, when I upgrade the package pve-qemu-kvm:amd64 from 10.0.2-4 to 10.1.2-1, if I use VNC in the guest system’s Display -> Clipboard section, the mouse becomes unusable in the NoVNC console on the guest.

When I downgrade, it works correctly again.

To fix the issue, I tried different display adapters such as Standard VGA, VMware Compatible, and Spice, but the problem persisted. It only gets resolved if I downgrade the package from 10.1.2-1 to 10.0.2-4.

I believe there is a problem in the latest update.

I have the same issues on NoVNC and Guacamole VNC connections.
Only on Windows VMs with spice-tools installed and Clipboard set to VNC.

Downgrading was the only way to resolve this for me as well.
