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.
