Thanks for your reply, the problem is not only mouse lag but also video
refresh with bigger lag, for the mouse probably is the vdagent if the
patches added by flex are different and not compatible but about the
video (or general) performance probably is a different problem.
I don't have any windows 8 vm, only some few dozen of windows 10 in
production with latest flexvdi spice guest tools, work correctly but
have lag on some animation like scrolling windows login page with image
full screen, video on medium/high resolution (but better then new
official driver) and occasion hang on windows logo during windows 10
major update (I don't know if is related to spice drivers/services or not).

Is there any vdagent testing build with all newer patches available
somewhere?
