Stopped working after a recent update to 5.16.2.

STEPS TO REPRODUCE
1. Open assign window shortcut dialog, set focus to shortcut text widget. 
2. press Meta+alt+0
3. ...

OBSERVED RESULT
some rubbish symbols in the text window, no shortcuts assign

EXPECTED RESULT
'META+ALT+0' assigned as a window shortcut

As far as I know, somewhere in the stack "Meta" is a shortcut for "Ctrl+Alt+Shift" (legacy?). So "Meta+Alt" would not work, but "Meta" alone should work.

Can you confirm?

Comment 3 s.v.savenko 2019-07-25 12:09:28 UTC

No. Meta alone does not work either. I attached a screenshot with what I see when trying to assing Meta+2 shortcut. Moreover Meta+Alt+2 used to work yet about a month ago. I still have that setup saved as a session and I can still use the Meta+Alt+[0-9] shortcuts for windows in that session. But I can not assign new ones.

What's your keyboard layout?

Comment 5 s.v.savenko 2019-07-25 13:57:43 UTC

`English (US).` Though if try to get it from console I get:
```
$ showconsolefont 
Couldn't get a file descriptor referring to the console
```

Comment 6 s.v.savenko 2020-06-27 22:19:55 UTC

This is still broken. No shortcut with Meta can be put in using the `Set Window Shortcut` widget. It looks like it is getting the keys on press cause the strange symbol appears in the shortcut window immediately after I press `Meta` (without releasing it), and then when I press some key the proper `Meta+Key` combination appears in the window.

This bug was reported against an outdated version of KWin. We have made many changes since the.
