Description Rafael Linux User 2023-12-14 21:19:08 UTC

SUMMARY
Since a few weeks ago (last Plasma update for openSUSE Tumbleweed) the key combination "Alt + Shift + Tab" doesn't work, it doesn't respond, so to get to the previous task window, I have to scroll through all the open windows until I get back to the task I was in. 

STEPS TO REPRODUCE
1. Log in Plasma with Wayland session
2. Open 3  applications windows
3. Press "Alt" and hold it,  while keying "Tab" to change to 3rd task window
4. Press "Alt + Shift" and hold them, while keying "Tab" to change to previous task window

OBSERVED RESULT
To show Change to previous task window doesn't work, nothing happens

EXPECTED RESULT
Plasma should cycle among the three task windows in reverse order

Thanks for your report!
I tried it in the latest tumbleweed version of openSUSE 20231213 and it worked as intended. Try switching to the latest version. 
There is a newer version of plasma so it may help.

Can reproduce.

Steps to reproduce:
1. Go to settings -> shortcuts -> kwin
2. Find walk through windows reverse
3. assign Alt+Shift+Tab as shortcut

Observed behavior:
Alt+Shift+Tab does not work.

So if you manually edit .config/kglobalshortcutsrc and change Tab to Backtab, then it works again.

After "sudo zypper dup", nothing changed about issue. I must add that I didn't change shortcuts for task switching, only global shortcuts for QMMP control.
