I think the weird resolution is from the window size. Other than that
I'm mostly seeing the same behaviour (not that long to launch though,
but I'm on arm64 with kvm). For the display getting turned on & off,
I've heard there are efifb, simple-framebuffer etc. which would make it
work seamlessly but I don't know much about how to get it done.

This is due to the Linux kernel, it enables and prefers the serial
console on arm64. If you don't add console=tty0, they won't get printed
to the framebuffer at all (on ACPI devices).

I tried that and see this happening too, but no idea what happens why.

(If you're still looking for `list-devices cd` it's probably actually
debian-installer-utils/list-devices-linux [1])

Yeah, happens frequently.
