SUMMARY During intense workflow in a Wayland session, I sometimes find that Alt+Tab walks through tasks in reverse order (upwards). In these cases, Alt+Shift+Tab still works as intended (upwards). The issue persists if I let the task switcher disappear and press Alt+Tab again. I can only deal with it until it goes back to its normal behaviour (downwards) a few minutes later. I don't know how to help you debug this, so I will accept any suggestions (including patches). I haven't experienced this issue in X11. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.69.0 Qt Version: 5.14.2 Kernel Version: 5.6.8-arch1-1 OS Type: 64-bit Processors: 4 × Intel® Core™ i5-6200U CPU @ 2.30GHz Memory: 11,6 GiB of RAM ADDITIONAL INFORMATION I am using the Wayland session as my default environment. Due to various issues, I request QT and GTK applications to run as X applications. So, I run Plasma in the following way: > GDK_BACKEND=x11 QT_QPA_PLATFORM=xcb startplasma-wayland I don't know if this is related with the issue, but it is very hard for me to work in a Wayland session without these settings. Basically, due to issues like bug 392376, any application can crash at any moment. XWayland clients are a lot more stable.
This issue report is quite old. Can you please confirm, that it still persists with KDE 5.23? If so, can you please describe steps on how to reliably reproduce this issue?

I used the Wayland session again after a very long time and experienced this issue again in Plasma 5.25.3. Therefore, I'm reopening this issue. I'm sorry that I cannot provide steps to reproduce this issue reliably, since it just happens all of a suden.
Does this still happen in Plasma 6? There have been a few changes around modifier handling for the tabbox, which might have fixed this
