I don’t want to be the bearer of not so good news, but I’m afraid there is still an undesirable behaviour with layouts switcher.
Whenever you’re switching from the Tiling layout to any other layout (I tested switching to the Manjaro and Gnome layouts though) the keyboard input stops working for me. I had to click Apply and then Reload desktop to get the keyboard input back up.
That does not happen switching among layouts other than Tiling. Just clicking Apply gets the job done and there is no need to Reload the desktop.
Note that I’m using wayland with open source video drivers (i915 modesetting + noveau).
I’m my opinion, I’m OK doing these 2 clicks to ensure proper layout switching. It might be not clear for everyone though.
