[Solved] Home/End keys require two keystrokes in gtk applications

Running linux 5.10.37-1-lts with with all packages updated to latest version on a Acer Chromebook 14 - CB3-431.

I use the xkeyboard-config from GalliumOS (which fixes several Chromebook quirks in general). The added xkb entries can found here. My config is:

$ setxkbmap -print -verbose 10
Setting verbose level to 10
locale is C
Trying to load rules file ./rules/evdev...
Trying to load rules file /usr/share/X11/xkb/rules/evdev...
Success.
Applied rules from evdev:
rules:      evdev
model:      chromebook_m
layout:     se
Trying to build keymap using the following components:
keycodes:   evdev+chromebook_m(media)+aliases(qwerty)
types:      complete
compat:     complete+chromebook
symbols:    pc+se+inet(evdev)+chromebook_m(overlay)
geometry:   pc(pc104)
xkb_keymap {
	xkb_keycodes  { include "evdev+chromebook_m(media)+aliases(qwerty)"	};
	xkb_types     { include "complete"	};
	xkb_compat    { include "complete+chromebook"	};
	xkb_symbols   { include "pc+se+inet(evdev)+chromebook_m(overlay)"	};
	xkb_geometry  { include "pc(pc104)"	};
};

To invoke Home, I hold down the Chromebook search key (which in my case corresponds to 'Overlay1') and press Left.

xev output:

$ xev -event keyboard

In gtk applications (I've tested firefox, galculator, gedit, xfce4-terminal) I need to hold down search key and press left arrow twice in order to move the cursor.  

$ galculator --gtk-debug keybindings

Re: [Solved] Home/End keys require two keystrokes in gtk applications

Try to "export GDK_CORE_DEVICE_EVENTS=1" (this is an absolute wild guess, typically the mouse wheel is affected, but gtk has weird input behavior habits and this usually skips them)

Re: [Solved] Home/End keys require two keystrokes in gtk applications

Some overzealous https://wiki.archlinux.org/title/Input_method ?

echo $GTK_IM_MODULE

Where did you export GDK_CORE_DEVICE_EVENTS btw (needs to be the parenting shell of the misbehaving client)

Output is blank.

I put it in .xinitrc (and restarted xfce4).

Oh I forgot, running 

startx /usr/bin/galculator

from Linux console produces the same results.

Re: [Solved] Home/End keys require two keystrokes in gtk applications

It's a gtk bug after all, introduced in 3.24.25. Bug report here: https://gitlab.gnome.org/GNOME/gtk/-/issues/3673. While waiting for a fix, downgrading to 3.24.24 solves it.
