SUMMARY STEPS TO REPRODUCE 1. Start with a fresh install (or Live-CD) 2. Go to Keyboard under System Settings, and select Layout *English (US)* with Variant *English (US, intl., with dead keys)* 3. Open two or more windows of the same program (e.g., Firefox), and let one of them be the active window 4. Press Alt+` to switch to another window of the program OBSERVED RESULT Nothing happens EXPECTED RESULT The shortcut should allow to switch between windows of the program, as always. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 18.04 KDE Plasma Version: 5.12.7 KDE Frameworks Version: 5.44.0 Qt Version: 5.9.5 ADDITIONAL INFORMATION Workaround: leave the first entry of Keyboard Layouts as English (US) (i.e., Default variant), and add the desired layout as a *second* entry. Apply changes, and then select the desired layout from the bottom toolbar. Now you can write with the layout that you chose, but the aforementioned shortcut still works as expected.
I use US and brazilian portuguese layouts. Alt+~ (default shortcut to walk through the current app in reverse order) only works when pressed twice. To walk through the current app in normal order, I need to press alt+shift+` twice even if the shortcut configured in TasK Switcher KCM is the default alt+`. Positioning US layout as the first one in Keyboard KCM did not help on my system.

Updated ticket data, as issue is still there on 5.27.4 on Fedora, as well as openSUSE tumbleweed (wayland only). When using US intl with dead keys (in a program like kate), you need to type a space after the ` (backtick) in order to get a backtick character, or type a second backtick. The same applies to window switching in kwin with Alt+`: when using US intl with dead keys you either have to press Alt+` twice or keep Alt key pressed, then type ` followed by a space (w/o releasing the Alt key). Keyboard layouts with dead keys should not cripple Alt+`. Note that this bug is only on Wayland, not with X (where Alt+` behaves the same in US and US intl with dead keys.)

As far as I can tell, this is just a special case of the more common bug 453661 which was fixed in Qt 6.6.0: https://bugreports.qt.io/browse/QTBUG-108761 Please correct me if I'm wrong. *** This bug has been marked as a duplicate of bug 453661 ***
So, the resolution to this will come with KDE 6.x ???
Yes
Apparently is a merge request for that has the patches for Qt5 https://invent.kde.org/qt/qt/qtbase/-/merge_requests/239
