--- Comment #6 from mata sutupud@yahoo.com --- Still no change in wine 10.4
I've tried to make some sense of those remappings, it seems to try to fix the layout internally, but the xcb layout should already do that. But even with that assumption it doesn't seem to work, e.g. it doesn't really translate a qwerty layout to qwertz if the lookup table is selected accordingly. And if that was required, it would need to have similar tables for any other potential layout.
The compositors with which I tried it are kwin_wayland, weston and sway - all with the same result.
Another minor problem I saw is that the numlock state can't be toggled. A while ago I remember it being stuck in off state, now it's always on. Not sure if that's somewhow related.
