Comment 4 for bug 1783987

I'm using the keyboard layout de-neo (German Neo2). When starting a x11 graphical application in a xwayland session, I see this error message printed to console or syslog:

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Error: Key <LFSH> added to map for multiple modifiers
> Using Lock, ignoring Shift.
Errors from xkbcomp are not fatal to the X server

When starting wayland graphical applications (using Gtk+ 3.20) I get this message:

xkbcommon: ERROR: Key "<LFSH>" added to modifier map for multiple modifiers; Using Lock, ignoring Shift

When starting a x11 session I get this message:

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning: Multiple interpretations of "Caps_Lock+AnyOfOrNone(all)"
> Using last definition for duplicate fields
> Warning: Multiple interpretations of "Shift_L+AnyOfOrNone(all)"
> Using last definition for duplicate fields
> Error: Key <HYPR> added to map for multiple modifiers
> Using Mod2, ignoring Mod4.
> Error: Key <MDSW> added to map for multiple modifiers
> Using Mod3, ignoring Mod5.
Errors from xkbcomp are not fatal to the X server

So it looks like this layout is broken. I have no idea what. Can you please give me a hint on the reason why this happens?

Upstream is at https://wiki.neo-layout.org/browser#linux/X/rules, but they don't seem to fix these warnings/errors: https://wiki.neo-layout.org/ticket/408

I'm running Fedora 24 with
xkeyboard-config-2.17-2.fc24.noarch
libxkbcommon-0.6.1-1.fc24.x86_64
