Shortcuts not working with Gnome/Linux

[lumbric]

When I hit the shortcut, nothing happens. I tried changing the shortcut, logging out from the Gnome session, but again: nothing happens when I hit the shortcut.

Flemozi is running:

$ ps aux|grep flem
MY_USER      30848  0.0  0.0   3648  1920 ?        SN   00:01   0:00 bwrap --args 42 flemozi
MY_USER      30857  0.0  0.0   3648  1152 ?        SN   00:01   0:00 bwrap --args 42 flemozi
MY_USER      30858  0.2  0.5 2477656 131376 ?      SNl  00:01   0:00 flemozi
MY_USER      32334  0.0  0.0  19020  2688 pts/1    S+   00:06   0:00 grep --color flem

And it cannot be run another time (because it complains about an existing lock file).

When being run on the command line as first process, it says:

$ flatpak run dev.krtirtho.Flemozi 
OnLoad
Gtk-Message: 00:09:24.738: Failed to load module "canberra-gtk-module"
Gtk-Message: 00:09:24.739: Failed to load module "canberra-gtk-module"

(flemozi:2): Gdk-CRITICAL **: 00:09:24.801: gdk_window_get_state: assertion 'GDK_IS_WINDOW (window)' failed

Is there any other way to open the window if it is already running?
Any suggestion how to debug this issue?

• Pop!_OS 22.04 LTS / Gnome, x11 (not Wayland)
• installed via flatpak
• flemozi 0.2.0
