I am using two keyboard layouts and if I configure layout shortcut to "alt+shift" then I am not able to use any shortcut combination that has alt+shift in it. For instance "reverse task switching" is not working also in other programs some shortcuts having alt+shift is not working too. In older versions of KDE I was able to use that shortcut along with others.
Cannot confirm on Arch Linux, plasma 5.12.4. I can set alt(left)+shift(left) shortcut to change keyboard layouts and alt+shift+tab shortcut is still working to toggle windows.
I have two laptops with identical setup and I face the problem in only one of them :/ More info here: https://forum.kde.org/viewtopic.php?f=289&t=151314

Hi, I'm facing the same issue with KDE Plasma 5.13.5, Debian Buster. In my case there are 2 different situations: 1. If I'm mapping ALT+SHIFT+TAB to the "reverse walk through windows" and I have also ALT+TAB for "walk through windows", KDE is doing only "walk through windows". 2. If I'm removing ALT+TAB, then KDE is trying to do "reverse walk through windows", but is stopping after first windows. Is not moving farther. My laptop is Asus G56JK series.
Hi, Becouse I couldn't reproduce the "back tab" from the keyboard, I've managed it by exporting the keyboard shortcuts from a VM and import them into my PC. Now the alt+shift+tab is working again. Kind regards, Adrian

Confirmed with Plasma 5.19 and Frameworks 5.71 on OpenSUSE Tumbleweed. STEPS TO REPRODUCE: 1. Set "Alt-Shift" as a hotkey for shifting keyboard layouts. 2. Open more than three programs. 3. Press Alt-Tab a few times and watch in which direction the task switching goes. 4. Press Alt-Shift-Tab. OBSERVED BEHAVIOUR Alt-Shift-Tab switches tasks in the same order as Alt-Tab. EXPECTED BEHAVIOUR Alt-Shift-Tab switches tasks in the opposite order as Alt-Tab.
This bug is really annoying, as it prevents people from using shortcuts in many popular apps. Whoever uses Alt+Tab for switching keyboard layout, is forced to use mouse or find out annoying workarounds. I believe this is not just usability issue, but also a serious accessibility problem then.
Still not working. Latest KDE Neon. Once ALT+SHIFT is used for keyboard layout switching, then reverse tabbing via apps using alt+shift+tab does not work.
I can confirm this bug even with brand new Plasma 5.21. Operating System: KDE neon 5.21 KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.11.0-051100-generic OS Type: 64-bit Graphics Platform: X11
This issue is not exclusive to Plasma. The root cause is in how X11/XKB handles the layout switching shortcuts and has been around since pretty much ever. See https://gitlab.freedesktop.org/xorg/xserver/-/issues/258

Not easily at least. The relevant component here, XKB, is used on Wayland as well

I'm pretty confident that "alt+shift+key" shortcuts used to work perfectly in KDE4 times. I had always "alt+shift" for layout shortcut in Kubuntu versions 10.x - 14.x. Thus there has to be some KDE-specific fix for that.

Lurking in the bug report link, it seems some distributions provide a patched version of XKB which solves this issue: https://bugs.gentoo.org/379827 https://aur.archlinux.org/packages/xorg-server-bug865/ Perhaps you were using one of those? I BTW recall testing XFCE some time ago in some live distro - don't remember which one - and it also seemed to have solved the issue somehow, while the MATE DE in the same distro did not. Could Kwin somehow incorporate the patch from the bugtracker without requiring a modified version of XKB?
This issue is still present with kwin 5.25.5 on Wayland, where the patched XOrg packages would not be helpful. Could there be a way to patch KWin on Wayland to work around this? This bug has existed in X for over 20 years (see Bug 59303), maybe it's time to get it fixed once and for all?
The default layout switching shortcuts are handled by xkb, and not by kwin. If you assign newly supported modifier-only shortcuts as an alternate shortcut for layout switching, they won't interfere with other shortcuts.
