German NEO2 Layout:

After huge plasma update the "zero" key on layer 4 (Mod3 + "Space") isn't working anymore.

It's registered as a "normal" space-keypress.

Other keys work normally on that layer.

Steps to Reproduce:
Open systemsettings->input devices->keyboard & add and select German/Neo 2 as a keyboard layout.

Actual Results:  
Pressing Mod3-Key + SPACE-Key returns " " not "0" as expected.

Expected Results:  
"0" should be returned

Other tests on WMs:
Expected behaviour on Hyprland (Wayland) and QTile (X11).

I cant get 0 with mod+3, but it works with mod4+space though. I've never used this layout but i looked at the guides here: https://www.neo-layout.org/

Typo in above:  mod+3 -> mod3+space

Sorry, got a little mixed up.

It's actually Mod4+SPACE, not Mod3.

So, you can't reproduce it?

According to the xkb layout description (https://github.com/xkbcommon/libxkbcommon/blob/a600c36d1bc21aa33e68c391a637cc396a4ecaeb/test/data/symbols/de#L416) and the info in the Neo Layout page (https://www.neo-layout.org/Layouts/neo/), to get a "0" with the Space key you need Mod4/Ebene4 (ISO Level5), not Mod3 (ISO Level3), which it is working.

Yep, can't reproduce the issue, might be fixed on the git master version

Note that the actual layout file is in another project, xkeyboard-config: https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/blob/63d45b4a84330eca6903963d37a6e50bc947c13d/symbols/de#L480. Files in xkbcommon repo are for testing purpose only.

I cannot reproduce the issue either, so let’s close it. If you face another issue about keyboard layouts, please open a ticket upstream directly at: https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/issues.
