External QMK keyboard misbehaves in Wayland session

I have a keyboard which has QMK firmware that works fine on Fedora 37 in an Xorg session. When I log into a Wayland session, the keyboard starts to misbehave. The main problem is that one shot layers act as modifiers (only modifies a key when held). I have looked around but haven’t seen anyone having the same problem and don’t know where to begin debugging something like this. Any help is much appreciated.

This seems to be an IBus issue: Keyboard input gets jumbled when typing fast · Issue #2486 · ibus/ibus · GitHub. I managed to solve a similar problem by adding the following lines:


to my ~/.config/environment.d/env.conf, which disables the IBus input method.
