Autocompletion doesn't work depending on unknown environment condition

Hello!

This is probably difficult to debug. With the default setup:

    "source_show_completion_comment": "Add completion keybinding to disable interactive autocompletion",
    "source_show_completion": "",

When I use Jucipp with my regular user, some environment condition prevents the opening of the autocomplete popover. No error message is shown. I'm forced to set a keybinding and use it manually.

Autocomplete works with a new user as intended! Also on another system with the same distribution (Arch), package versions (GNOME 48), and a nearly identical setup.

My guess is that some external setting—which I'm not aware of—causes this. Is there a related Gtk setting that could cause this?

What I've tried:

• rm -r ~/.juci
• Inspect STDOUT/STDERR output of Jucipp
• Inspect at log messages at bottom of Jucipp
• Setup new project with meson and with cmake

I could delete my user and setup the account again. But I think it is better figure out the cause and document it.

Thank you
