SUMMARY I just started testing the new Plasma 5.15 beta and already found a bug : I cannot navigate through windows in Task switcher by clicking Alt + Tab. It works the first time (the effect starts), but then navigating is impossible if I keep one finger on the Alt Key and tap the Tab key with my other finger. I can navigate with the arrow keys, though, it works that way. I'm on Wayland but I don't think that's relevant. This bug is specific to Plasma 5.14.90. STEPS TO REPRODUCE 1. Press Alt + Tab to activate task switcher 2. keep a finger pressed on the "Alt" key and tap the "Tab" key multiple times 3. Nothing happens OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: MacOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.14.90 KDE Frameworks Version: 5.54 Qt Version: 5.12 ADDITIONAL INFORMATION

I provided the needed information.
Works for me FWIW.
Have the same problem on latest kde neon, if you want same info please ask
same problem here - bug 400658 shotcuts of task switcher frequently stop working, it's a very annoying problem.
Same problem here. I am using Wayland. KDE Plasma: 5.15.3 KDE Frameworks: 5.56.0 KDE Applications: 18.12.3 Qt: 5.12.1
I have created a new user and realized that the new user is not affected by this problem. After I removed and recreated the user again, I copied all .config/k* files from my normal user to this test user (chmod, ...). The problem exists for the new user, too. I tried a binary search (not exactly but similar) to detect the configuration file(s) that causes the problem. ATM I can reproduce the problem if I use that configuration files of the other user: === kcmdisplayrc kcmfonts kcminputrc kcmshell5rc kconf_updaterc kdebugrc kdeconnectdrc kded5rc kded_device_automounterrc kdeglobals kdeveloprc kglobalshortcutsrc khotkeysrc === Need to check now every one step by step...
My .config/kcminputrc contains that keyboard section: === [Keyboard] KeyboardRepeating=0 NumLock=0 RepeatDelay=600 RepeatRate=25 === I don't know what's wrong here, but if I remove that keyboard section the Alt + Tab behaves as normal.

Same here. The problem is numlock setting in system settings > input devices > keyboard. When I set numlock to "Off" or "Unchanged", both alt+tab and alt+' shortcuts work as expected. When I set it to "On", the same shortcuts fail. Operating System: Arch Linux KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2
