Comment 17 for bug 2000739

@Markus
Hi,
on one hand on today's retry I've found it to go fullscreen correctly (even without GTK_BACKEND=x11 set). The top bar moves up to the correct place. I wondered and looked more at is, so I found that "fullscreen" works more reliable if the guest resolution isn't matching the real screen resolution. Due to scaling it doesn't look as nice, but I've found same-resolution going fullscreen more likely to expose issues. When it is on the same resolution I still can sometimes see it dropping decorations but stay "in-place". It almost seems that it is confused by thinking "huh I'm already at the target size with my panel" and then does not to the scaling/maximization.

Seeing that I'm curious how this behaves on a single screen, have you ever had the chance to try this on a single screen computer?

Also have you seen that it works better when not using the native resolution of the display?
