Description Michail Vourlakos 2018-08-04 14:29:55 UTC 
Just to have bug tracking for this. As the title says the PresentWindows effect  that is used for grouped tasks under X11 it would be nice to have for plasma-related taskmanagers
Comment 1 Alexander Mentyu 2018-08-06 14:12:23 UTC 
Present Windows effect isn't triggered after clicking grouped windows in Task Manager in X11 and Wayland. How to enable it - Present Windows effect is enabled in Desktop Effects

Kernel: 4.15.0-29-generic
Plasma: 5.13.80
Apps: 18.11.70

Until this is supported, is it worth adjusting the warning text to note this? (Currently, it's "The 'Present Windows' effect is not enabled or otherwise available right now, so a textual list will be displayed instead"). Or perhaps disable this menu entry under Wayland altogether.

Use DBus interface for presentWindows

Similiar to highlightWindow the effect has gained a DBus interface
in order to also support wayland.

Comment 7 David Warner 2021-06-09 15:20:02 UTC 
Should this work out of the box in 5.22? I still see "The 'Present Windows' effect is not enabled or otherwise available right now, so a textual list will be displayed instead".
Comment 8 Nate Graham 2021-06-09 16:19:29 UTC 
It should be. It's working for me FWIW.
Comment 9 Patrick Silva 2021-06-09 18:14:59 UTC 
works for me on Arch Linux too. Tested both icon-only and classic task managers.
Comment 10 David Warner 2021-06-09 23:50:20 UTC 
Thank you, this was pure PEBKAC. I can confirm this is working.
