Keyboard layout config scheenshot

Using wayland session on latest Neon User Edition with two keyboard layouts configured.
When I type in some Qt app (like KWrite) layout switching works as expected: it switches right after shortcut press.
But after pressing shortcut in xwayland app (I tried firefox, sublime text, pgadmin3) layout remains the same and changes only when I move focus to another window and return it back.
And one more thing - when pressing layout switching shortcut two times it changes layout but only until I move focus to another window.

Attached my keyboard layout screenshot

How do you switch layouts? Do you use a shortcut set in the keymap options or the global shortcut (ctrl+alt+k) provided by Plasma?

I've configured Caps Lock key as a shortcut in System Settings>Input Devices>Keyboard>Layouts (as on attached image). I thought this is the only way to configure it in Plasma :)

This is unfortunately a known issue in older XWayland - it is fixed with XWayland 1.19, you only have 1.18. If you switch with the global shortcut it works, though.

Yes, installing xwayland-hwe-16.04 package fixes the problem. Thank you.
Martin, do you know whether this package will be included by default in Neon 5.12?

Sorry, I don't know.
