Keyboard shortcuts using Super modifier work only on primary keyboard layout (whichever layout is listed first in layouts)

[sedmicha]

I have posted the following issue to MATE and later found out that this is caused by mintmenu:

I have noticed an issue that some of my keyboard shortcuts do not always register. I use two keyboard layouts that I switch between and I found out that it only happens when I'm switched to the other keyboard layout and when the shortcut uses super as a modifier.

I thought that the particular layout might be the issue, but I have tested that this happens regardless of what the other layout is. The only thing that matters is the index of the layout in the layouts dialog. The shortcuts work when the layout in use is the layout that's listed on the first position in the layouts dialog. If the selected layout is a layout that is listed second, third, ... in the list of layouts, the keyboard shortcuts do not work. If I move the layout to the top, the shortcuts start working on that layout and stop working on the one that is now second.

I also thought that the issue might have something to do with using Super+Space as the key combination to switch layouts, but I have tried other combinations and this happens regardless.

Expected behaviour

Keyboard shortcuts using Super as a modifier work regardless of the chosen layout

Actual behaviour

Keyboard shortcuts using Super as a modifier only work if the selected layout is listed on the first place in the keyboard layouts dialog

Steps to reproduce the behaviour

• Have a keyboard shortcut that uses Super as a modifier, for example Super+Up to maximize a window
• Open Keyboard preferences and navigate to the Layouts dialog
• Add another layout to have at least two, for example English and German, such that English is listed first and German second
• Switch to English layout
• Pressing Super+Up maximizes the window as intended
• Switch to German layout
• Pressing Super+Up does nothing
• Now use the 'Move up' button to reorder the layouts such that German is listed first and English second
• Switch to German layout
• Pressing Super+Up maximizes the window as intended
• Switch to English layout
• Pressing Super+Up does nothing
