--- Comment #5 from pinkfluid@gmail.com --- Took some time before I figured I need to do autoreconf && tools/make_requests between each bisection, but so far it seems that this patch seems to be the culprit:
-- winex11.drv: Listen to RawMotion and RawButton* events in the desktop thread.
Virtual desktop works with the patch prior to this and breaks when this one is applied.
I can attach the git bisection log if it contains any helpful information.
