Sorry, I didn't read properly - so first check if you have
spice-vdagentd up'n'running in all the linux guest. It should be part of
all distributions but I wouldn't be surprised if it wasn't installed by
default.

Second, if the problems persist, you can try to disable surfaces:

# cat /etc/X11/xorg.conf.d/qxl.conf 
Section "Device"
         Identifier  "qxl"
         Driver      "qxl"
         #Option  "DPI"   "96 x 96"
         #Option "ENABLE_IMAGE_CACHE" "True"
         #Option "ENABLE_FALLBACK_CACHE" "False"
         Option "ENABLE_SURFACES" "False"
EndSection
