Description Clarence Risher 2020-03-24 10:27:06 UTC

SUMMARY
I am setting up my Alternative task switcher shortcuts to use meta+tab and meta+shift+tab, similar to Gnome. This has brought to my attention that this combination does not function equivalently to alt+tab, instead allowing only a single press of tab per press of meta.

STEPS TO REPRODUCE
1. Set keyboard shortcut for Walk Through Windows (Forward) to meta+tab
2. press meta
3. press tab
4. release tab
5. press tab
6. release tab
7. release meta

OBSERVED RESULT
second press of tab has no effect

EXPECTED RESULT
second press of tab should walk to the next window again, similar to the behavior if this shortcut was alt+tab

Wayland or X11?

Comment 2 Clarence Risher 2020-03-24 17:11:33 UTC

X11
arch package xorg-server version 1.20.7-1

Comment 3 ndesroches88 2020-08-22 20:54:45 UTC

I was having the same issue on Manjaro, setting the shortcut then rebooting fixed it for me.

Comment 4 Henrique Sant'Anna 2021-02-08 19:57:37 UTC

I can confirm that once set the shortcut Meta + Tab for Task Switcher (Main or Alternative) it will change between windows only once, no matter the effect selected for the switcher.

And I can confirm that restarting computer (comment3) will fix the issue and, from that, Meta + Tab will than work to change between windows multiple times, as expected.

Comment 5 Henrique Sant'Anna 2021-05-20 02:12:51 UTC

Tested with Plasma 5.21.5 (Wayland), still an issue.

If I change the shortcut it only works for changing one window.
If I change the shortcut back to the old value it works multiple times in sequence, for changing between multiple windows.

Restarting will fix the behavior for a new set shortcut.

Comment 6 Andrei Rybak 2023-10-07 17:04:44 UTC

I use:

- Meta+Tab for "Walk Through Windows Alternative" 
- Meta+Shift+Tab for "Walk Through Windows Alternative (Reverse)"

Regardless of the animation selected in dropdown "System Settings > Workspace > Window Management > Task Switcher > Alternative > Visualisation", for me, Meta+Tab works fine, but Meta+Shift+Tab only works _once_ (can change only to the immediately previous window) and only when it is pressed _first_ (i.e. pressing the reverse after Meta+Tab doesn't do anything).

This no longer seems to happen as of plasma 6.0 on either x11 or wayland, so marking as fixed.
