AltGr (dead keys) display an error in main buffers and is not usable in minibuffer about emacs

@A6GibKm Does your pgtk emacs behave as the same?

I think it would be helpful to know what keyboard layout is being used. I have two keyboards: a spanish one where it works as intended, i.e. ' a produces á, and a US one where I use US Intl with AltGr dead keys and it also works as intended (Altgr + a produces 'á'). I don't know of a layout where ´ is invoked using AltGr.

I don't know of a layout where ´ is invoked using AltGr.

@CRCulver What layout do you use?

I am using a custom keymap, which I originally created in X11. It is defined in an XKB file which I have attached here. Now I use Wayland and the Sway window manager. Sway has support for loading XKB files through thexkb_file command in its configuration file
xkb.dump.txt

I should mention that input works in all other GTK3 applications under Wayland. This branch of Emacs is the only application where I am experiencing a problem.

Thanks for the dump file. I tested it on sway, and confirmed that the warning appears on the minibuffer, but the timing is different.
I'll debug the warning of my case for now.

@CRCulver
Gtk's modifier keys seem to be different from Xlib's ones,
and the AltGr key was incorrectly handled.

It should be fixed in #54. Could you try it?

[CRCulver]

Thank you very much, #54 fixes this issue for me. You may close this issue now if you want.

thank you!
