[Impact]

 * When running a Windows VM using the QXL driver from [1] the display is inverted and therefore almost unusable.

[Test Case]

 * Launch a Windows VM with a QXL display (I used Win2k16 running under libvirt).
 * Start websockify
     sudo apt install python3-websockify && websockify 5959 localhost:5900
 * Run a HTTP server to spice-html5:
   cd /usr/share/spice-html5 && python -m SimpleHTTPServer
 * Open a browser and go to http://localhost:8000
 * Enter
   host: localhost
   port: 5959
 * Click start

Expected behaviour:
Guest UI is displayed correctly.

Actual behaviour:
Guest UI gets inverted on refresh.

[Regression Potential]

 * This component may be used with openstack and it's possible that there are workarounds in place, so they may start working incorrectly.

[Other Info]

 * This is fixed from cosmic onwards (spice-html5 0.1.7-3).
