Doesn't reproduce too.  It's also not clear why x86_64 should behave
different that ppc.  There is no arch-specific code ui/, so there should
be no difference, exept for hardware like paralle ports which are not
supported by all machine types.

Any chance you have tested an old ppc binary?

Not likely because I did make distclean and a clean build before testing
to avoid any possible mismatch. It still does not work for me though.
While

I still have this problem after updating everything on my machine, latest
QEMU and SDL 2.0.9 so it's not likely to be a bug in some external
component. If I just start qemu-system-ppc (compiled with --disable-gtk) and
try to open monitor console with Ctrl-Alt-2 I see QEMU monitor but when I
type in this window the serial output window contents flash in this window.
At the same time the window that opens for Ctrl-Alt-3 which should have the
serial output is empty. It looks like an index may be off somewhere or
window contents are not associated with the right window but I have no idea
where to look for it. Can you reproduce it now and do you have any idea what
could cause this?

Could you share an example command line which can be used to reproduce
the problem.

As I wrote above ust "qemu-system-ppc" without any options reproduces the problem here.
