You seem to be using a PGTK build. Please see if you get different
behavior differently on a build with the regular X Windows support.
Thanks.
If you're using X, don't use PGTK. It lacks certain features, such as
drag and drop support, which will require a rewrite of the selection
handling code to use GDK selections instead of the GTK clipboard,
working `yank-media', and is known to cause many problems related to
input.
BTW, some of your configuration options are redundant or make no sense:
--with-wide-int does nothing on a 64-bit system, and --with-xft,
--with-cairo and --with-x-toolkit=gtk3 are ignored when PGTK is enabled.
You might want to correct them.
