Unwanted responses to use of the Meta key alone

My preferred shortcut for the Application Dashboard:

Control-Alt-Space​

Problem

The dashboard appears in response to the Meta (Windows) key alone.

What might cause this?

Scope

It's not just the Application Dashboard.

If (instead) I assign Control-Alt-Space to the Application Launcher, then the launcher appears in response to the Meta key alone.

If I clear the shortcut, which does not use the Meta key, then ☑ the Meta key has no effect.
 
You can try x11/xev to see what X11 should get by a keypress. Launching the program opens a window. Move the cursor to the window. Then the console should print information related to mouse events, key press and such.

With x11/xkbset one can change the key codes. May be this is done somewhere or there are different mechanism which can be used to change the codes. It can be that this post is superfluous because you are no newcomer and know that already :).
 
Output from xev includes (when I press the key, before I release):

Code: 
KeyPress event, serial 40, synthetic NO, window 0x9e00001,
    root 0x713, subw 0x9e00002, time 104623269, (45,38), root:(768,322),
    state 0x0, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False
 
This output is almost similar here.
Code: 
KeyPress event, serial 36, synthetic NO, window 0x1000001,
    root 0x2e8, subw 0x0, time 483475, (100,1), root:(102,63),
    state 0x0, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False
The combination of CTRL-ALT-SPACE gives an output for each key. Unfortunately I am not familiar with KDE. At least it was worth to try.
 
On a notebook with Manjaro KDE the gui settings for the keyboard shortcuts are stored in $HOME/.config/kglobalshortcutsrc
Elsewhere it may be stored under $HOME/.kde/share/config or the like. So one has just to look for kglobalshortcutsrc to find the right place.

I remember back in the past, I used xmodmap in fvwm2 to remap keys. It may still work in X11, but not in Wayland, I assume. However, adding and loading an extra .Xmodmap file might be in conflict with the KDE settings.

Looks OK to me:
