Comment 11 for bug 1896250

Ha, I found something that fells like a stuck guest with Ubuntu as well, but it wasn't "as stuck as Android".
I have found after a while that it seems infinitely happy to run without focus (no mouse / keyboard events getting to the guest).
But when I focus the guest sometimes the glxgears in the guest seemed stuck.

It almost seems like the host needs a "bump" to realize the guest still writes.
glxgears FPS usually are at 180-200 for me.
In those stutter moments they drop to ~5-20 FPS.

To give the host the bump for me it always worked to leave the guest mouse-capture (CTRL+ALT+G) and select and other window on the host. That made it realize "oh there is content" and things moved correctly again.

I'm unsure to what extend that is the same or a different problem, so I'm not going much further down this route.

Next:_ trying android ISO without sound device (and trying the host focus trick).
