When the VM is about to enter GUI desktop or quit the system, the screen turns upside down.
Description of problem:
When the VM is about to enter GUI desktop, the remaining booting message on the screen turns upside down. I was wondering if it is a designed feature or a bug. I like it because when I see it I'm ensured I'll enter the VM's GUI desktop soon without any problem.

An edit: This happens also at the quitting time when I type "sudo shutdown now" in the terminal.
Steps to reproduce:
1. Build qemu using the following `./configure` options:
```
--prefix=$HOME/.bin --target-list=x86_64-softmmu --enable-kvm --enable-vnc --enable-gtk --enable-vte --enable-xkbcommon --enable-sdl --enable-spice --enable-spice-protocol --enable-virglrenderer --enable-opengl --enable-guest-agent --enable-avx2 --enable-avx512f --enable-hax --enable-system --enable-linux-user --enable-libssh --enable-linux-aio --enable-linux-io-uring --enable-modules --enable-gio --enable-fuse --enable-fuse-lseek
```
2. Install Red Hat Enterprise Linux 8.5 in qemu
3. Run qemu using the above command line, or type "sudo shutdown now" in the terminal after VM starts.
