Created attachment 147511 [details] Tooltips/thumbnails not showing Tooltips/thumbnails often show under wayland but sometimes they do not until plasmashell is restarted. This problem exists only on wayland.
Same bug on Arch Linux (Plasma 5.24.3) and neon unstable.
Same here, but I could never see a single window thumbnail/miniature on task manager tooltips when running under Wayland. The animated content of the windows can be seen in the task switcher though. KDE Plasma v5.26.0 KDE Frameworks v5.98.0 QT v5.15.6 Wayland
D you have the kpipewire package installed?
(In reply to Nate Graham from comment #3) > D you have the kpipewire package installed? No: in Debian the such package doesn't exist, not even in sid or experimental (testing here). Is it required to have the miniatures?
Yep. That would be the problem, then. You could point the packagers at https://community.kde.org/Distributions/Packaging_Recommendations (kpipewire is a Plasma package, and as such, we recommend installing it by default).

Thanks Nate, it worked! I remembered that there is a kpipewire _source_ package (https://tracker.debian.org/pkg/kpipewire), which entered one week ago in the repositories: by installing the qml-module-org-kde-pipewire package along with the libraries it depends on I got the miniatures. Notice that no KDE Plasma package depends on those packages. Could you please clarify why are those libraries needed for the task manager, while the task switcher can display the miniatures without?
The implementation of thumbnails is different on Wayland compared to X11. I don't know what technical requirements of limitations prompted this, though.
