The windows freeze still happen (is not related to Javier changes).
Can someone tell me if also have windows freeze with qxl-dod driver please?
Happen mainly browsing websites with videos, I use xen, spice with
streaming  disabled, windows 10 pro 64 bit guest.
Probably is useful to know if happen or not with different enviroment.

Thanks for any reply and sorry for my bad english.
