Original commit message(s)

  • libtaskmanager: Listen for sycoca changes in WaylandTasksModel

XWindowTasksModel listened for them but Wayland did not. This ensures that editing an application is reflected live.

Basically copied from there.

Reason for the change

Changed an app icon of a pinned app in kmenuedit, didn’t take effect until I restarted plasmashell

Test plan

See above. With this, this works now.
