0. emacs -Q
1. evaluate this sexp:
   (let ((use-system-tooltips))
     (tooltip-show "Test"))
=> The shell outputs the following:

(emacs-master:8307): Gtk-CRITICAL **: 10:52:36.874: gtk_widget_set_app_paintable: assertion 'GTK_IS_WIDGET (widget)' failed

(emacs-master:8307): Gtk-CRITICAL **: 10:52:36.879: gtk_im_context_set_cursor_location: assertion 'GTK_IS_IM_CONTEXT (context)' failed

(emacs-master:8307): Gtk-CRITICAL **: 10:52:36.883: gtk_im_context_set_cursor_location: assertion 'GTK_IS_IM_CONTEXT (context)' failed

This does not happen with emacs-28 (and also doesn't happen in master
with non-nil use-system-tooltips).

This should now be fixed on master.

Likewise.

BTW, would people install libXi(-devel), configure with
`--with-xinput2', and use the resulting Emacs for a while?  It should
be stable enough for daily use, but there are certainly minor bugs
remaining that have to be ironed out, and I can't do that alone.

Thanks.

I confirm the warnings are gone now; thanks.

Is Xinput2 intended to replace Xinput, or is it only for use with touch
pads, touch screens or mice with multiple buttons?

Thanks, I'm closing this bug report.

We never used the original XInput API, but yes, it's supposed to replace
both Core Input (which we did use) and the original XInput on all
supported X servers once it's solid enough.

When building with XInput 2 support, the legacy code will remain for the
foreseeable future, but will be disabled if the X server supports XInput
2.
