Hi,

1. Letting the VM-viewer window-system draw the cursor as it normally

would draw it.

Why is this important? Can't the VM viewer hide the cursor and use a sub-surface to manually draw the cursor plane configured by the guest?

This would also allow the compositor running inside the VM to correctly have control over the cursor position, which is necessary for pointer constraints.

Aren't pointer motion events delivered in absolute and not relative coordinates in the "seamless mode"?

Do we do pointer constraints also with absolute motion?

Thanks, pq
