Description Oliver Sander 2022-06-17 08:18:05 UTC

Created attachment 149841 [details]
Screenshot of the relevant part of the 'settings' dialog.

My laptop computer has a German keyboard.  When I log into a Wayland session, however, the layout is English for all (many?) non-KDE programs.  This includes in particular Thunderbird, Firefox, and the 'Element' Matrix chat client.

I can get a German layout with the following steps:
1. Open the 'keyboard' part of the system settings program
2. Switch to the second tab ('Belegungen' / Layout(?))
3. Tick the checkbox 'setup layouts' (my translation.  In German: 'Belegungen einrichten').
4. Press apply.

Curiously, it doesn't seem to matter whether the checkbox is ticked or unticked, as long as I can press 'apply' once.

I'll upload a screenshot of the settings dialong, because I am not sure about the English names.

https://bugs.kde.org/show_bug.cgi?id=412101 seems closely related, but it is marked as 'fixed'.

Are these apps Wayland or XWayland clients? You can check with "xwininfo" and point to the window

Comment 2 Oliver Sander 2022-06-20 19:53:07 UTC

Does xwininfo needs some special options to display?  I don't see anything related to window managers in its output (see below).

In any case, as far as I know these windows are XWayland.

~> xwininfo 

xwininfo: Please select the window about which you
          would like information by clicking the
          mouse in that window.

Comment 3 Andrey 2022-06-21 09:58:03 UTC

The clue is if xwininfo doesn't show you any information when you click on a window, this is a Wayland window then. You can test on other clients.
Considering your output, you dealt with XWayland apps instead.

So you could try to run FF natively on Wayland and you shouldn't get the issue there.

Comment 4 Oliver Sander 2022-06-24 19:52:24 UTC

When running firefox and thunderbird with MOZ_ENABLE_WAYLAND=1 I indeed do not have the problem.

However, neither program then respects the KDE screen scaling setting, and they become very strenous to use on my hidpi screen.
