Hello all,

I am experiencing two issues with the language switching functionality.

1. Switching keyboard layout affects task switcher's behaviour.
Under System Settings > Hardware > Input Devices > Keyboard, on the Advanced tab, option Switching to another layout, I select Left Alt+Left Shift.
The configuration of the task switcher is the default one.

Alt+Tab works fine to forward switch tasks, but Alt+Shirt+Backtab breaks and does nothing.
After removing the Left Alt+Left Shift from language switching, the Alt+Shirt+Backtab reverse task switching works fine.

Is this an expected behaviour?

2. The onscreen display that should show up when switching languages does not show up anymore.
This was working fine, but suddenly it stopped and I have no clue where to look for issues.
The rest of the onscreen display messages, like for audio increase/decrease shows up normally.

It might be a configuration file that got messed up, any ideas?
