Qtvirtualkeyboard is shown, but input not working on the login screen

Hello.
I need to virtual keyboard on login screen, I added InputMethod=qtvirtualkeyboard to /etc/sddm.conf then virtual keyboard is appears, but input not working - I can click on keys, but there are no chars in password field.
Its not working on login screen but working fine on Lock screen.

Im try:
reinstall qtvirtualkeyboard, sddm, plasma-desktop, libibus.
clear /var/lib/sddm.
copy sddm and X11 configs from fresh installation.

Any ideas?

Thanks.

Its seems to be a problem with dual screens config.
qtvirtualkeyboard works on the second screen but not on the first.

I have set InputMethod=qtvirtualkeyboard in:
/usr/lib/sddm/sddm.conf.d
/etc/sddm.conf.d
/etc/sddm.conf

But nothing changed.

Log just say:
sddm-greeter: input method is not set

to make virtual keyboard appears, you have to set edit field focused… so firstly to click inside the field and next click virtual keyboard button

I got the same problem after upgrade to KDE6. Everything was OK before upgrade.
At first keyboard even did not appear on pressing virtual keyboard button (though the screen shifted up as if the keyboard appeared).
Then I added

[General]
InputMethod=qtvirtualkeyboard

to /etc/sddm.conf

and keyboard appeared but it does not insert typed letters to password field.
Though it works fine on Lock screen.
I also have double-monitor configuration, but I had it before upgrade also and everything was OK.
