When HUD is enabled and keyboard is set to greek, needs Alt-Tab twice to switch windows

[akarelas]

When HUD is enabled from inside MATE tweak, and keyboard is set to greek (and you switch keyboards with left alt left shift), ubuntun mate needs Alt-Tab twice to switch windows, instead of only once.

Why? I think this is a bug.

I can confirm the same behavior with german/us layout.

This seems to be an issue with how the HUD sends events forward to interact with some part of the keyboard layout manager (most likely in the mate-settings-daemon, but could be elsewhere). Regardless of which language set you have, only the first/primary works properly with the HUD, every other layout has this issue.

I'm investigating...
