Check for any errors in /var/log/libvirt/qemu/$vmname.log (qemu might be
reporting something)

Try a different VM video card (vga or qxl), adding or removing the usb tablet
pointer, maybe try switching to spice.

Besides that, yum downgrade all the Xorg packages in the guest and see if it
makes any difference.
