GTK + Wayland: Keyboard shortcuts not adapting non-Qwerty keyboard layout (Dvarok)

Hi,

I recently started using Dvarok full time, and some (all GTK) software in Ubuntu fails to identify the changed layout when shortcuts (Ctrl + C, Ctrl + X, Ctrl + V etc) are pressed. For example, Ctrl + X makes text bold in Geary, as X is positioned where B would be in a Qwerty. In all GTK software Ctrl + V offers me to input emojis, but doesn't paste anything.

Other software where I notice the same behaviour is Nautilus, the Gnome terminal, Ubuntu Software, Gnome Maps, Gnome Weather, Gnome Calendar, and the default Calculator. All non-gtk software behaves normally (such as Rstudio, LibreOffice, Atom, and FireFox).

I'm currently running a Flatpak version of Geary installed in 18.04, while the rest are from default repositories. The behaviour is the same.

Ctrl + Shift + C enters "^C" in the terminal, while Ctrl + Shift + J copies.

I have rebooted the computer many times since switching to Dvarok.

EDIT: The issue is connected to Wayland - after switching to X all applications behave normally.

Sorry for not knowing the appropriate place to lodge this bug, or if it's a duplicate.

Thanks for your work!
