Nope, I can reproduce it with sway as well (which is another Wayland compositor). To reproduce it with sway, just do: swaymsg "output * dpms off" and then should you see "Guest disabled display", at that point I'm unable to get back image. I tried the sendkey ctrl-alt-f2 and then switch back to TTY1 but the "Guest disabled display" remains. Can you please tell me which compositor you used?

I can still reboot the VM but that's not optimal. I can reproduce this with the latest QEMU release (5.0.0) or git master, = I also tried this with older releases (4.0.0, 3.0.0) and the issue is sti= ll there. I can't reproduce this with other video drivers (std, qxl). With std/qxl the screen will blank a bit and then continue as normal.
