Bug 335445

I try to configure the hotkeys of kwin and yakuake in plasma next with the graphical tools. I a heavy user of the key with the windows symbol, but if i press this key it is recognized as normal key and not as meta key.

Reproducible: Always

Steps to Reproduce:
1. go to systemsettings
2. go to hotkey configuration
3. try to configure some global hotkey
4. press the windows key
Actual Results:  
some boxes appear, like a unicode char, that has no visual representation and the dialog closes, so you can't press another key.

Expected Results:  
it should be recognized as meta key, so you can press other keys (e.g. meta-a)

I use the actual git head of kde-frameworks/kwin/yakuake/konsole/systemsettings.
