I'm afraid without any additional information there's not a lot on going on here. Can you open a Jira ticket and add the entire journalctl from the VM? Did you actually moved your cursor mouse? Have you tried not sending input to the VM at all and time it out to see how much does it take? We update the clock each minute so that's when a new repaint is happening.

Is the display powered up at all? Not sure if this is related to DPMS or the display not being enabled by the underlying hardware.

Guess you can do a paste a journalctl from when this works and when it does not and compare the two? glmark2 repains the screen the entire time, whereas only the clock might update it.
