Does the same thing happen if you minimize all windows by setting a global shortcut for the "MinimizeAll" action in System Settings > Shortcuts > KWin?

Sorry, but I cannot find this shortcut in System settings

Comment 3 Nate Graham 2022-05-04 17:34:54 UTC

Ah sorry, I forgot that you first have to enable the relevant KWin script in System Settings > Window Management > KWin Scripts. Can you enable it there, then try with the shortcut?

Ok, I tried it, and it apparently restores windows in the right order.

Thanks! Moving to KWin since the minimize/unminimize all code that the applet calls lives there.

Cannot reproduce, FWIW.

Comment 6 Peter Shkenev 2022-05-06 11:56:21 UTC

I also reproduced this bug in Artix.
Apparently it can be reproduced in X11, not in Wayland session.

Comment 7 Yaroslav Sidlovsky 2022-05-06 14:36:11 UTC

I'm able to reproduce this bug on X11 with plasma-5.24.5.

Strange that this applet just not calling KWin minimize all / restore all action via DBus (Meta+D by default, if I remember correctly),
this action restores windows in correct order.
