  Target Milestone: ---
    Classification: Fedora

After a recent update fedora regressed and is no longer possible to login
normally with diacritics in the password field.

Apparently was a regression in IBUS and it was fixed already upstream but at
least not yet in current fedora silverblue 43.

Reproducible: Always

Steps to Reproduce:
1. Use diacritics in the password of a user.
2. Try to login in GDM right after booting with diacritics in the password.
Actual Results:
Diacritics don't work properly.

Expected Results:
Should be able to use diacritics in the password field.

Do you use the latest ibus?
Currently ibus-1.5.33-5.fc43 is available.

The necessary changes have already been backported to f43 ibus.
You might not restart ibus or reboot the system for gdm.

Could you show the results of the following commands when GDM login screen is
shown?

ps -ef | grep ibus
rpm -qf /usr/libexec/ibus-engine-simple
ldd /usr/libexec/ibus-engine-simple | grep libibus
rpm -qf /lib64/libibus-1.0.so.5
locale
cat /etc/X11/xorg.conf.d/00-keyboard.conf
ps -ef | grep gnome-shell
rpm -qf /usr/bin/gnome-shell
ls /var/lib/gdm/.cache

It's not clarified how to input the password but I guess you typed your
password on the GDM password GUI entry with your keyboard.
And also the diacritics password is not clarified.

GDM password entry has an eye button and if you click the button, GDM shows the
password and can you clarify which characters cannot be output?

I'm using a physical keyboard on GDM.

For example this one worked before instantly: é

But let me clarify that after a few seconds of wait it starts to work, so it's
every time the pc boots to GDM that it doesn't work in that instant and have to
wait maybe 10 or 15 seconds, this didn't happen before.

I have discovered that it doesn't happen on a different tty as soon as GDM
shows up and I switch tty it works correctly on the new tty and I can switch
back to GDM and it still doesn't work until after a few seconds when before it
worked instantly.

Screencast of GDM

Seems I don't find obvious errors in your attachment #attach_2123644 while I
think your gnome-shell version is a little old.

Probably you need to update packages with:
`sudo dnf update gdm gnome-shell mutter gtk4`

```
% rpm -q gdm gnome-shell mutter gtk4
gdm-49.2-2.fc43.x86_64
gnome-shell-49.3-2.fc43.x86_64
mutter-49.2-2.fc43.x86_64
gtk4-4.20.3-1.fc43.x86_64
```

I follows your environment but cannot reproduce your issue.
Attaching the log of the screencast.
