That's right my bad, However it is always true in QxlDevice in  flexVDI's
repository
while it is always false in gitlab's repository.

When it is false - as in the current gitlab repository - the driver keeps
sending
unnecessary mouse info to the spice server which I believe is the cause for
the poor performance issues.

So Fabio can you please try using the driver with EnablePointer - the one
that's
in Qxl device class - set to TRUE as it is in flexVDI's repository?
