Created attachment 152157 [details] Screenshot SUMMARY I get no window previews in Plasma panel popups. STEPS TO REPRODUCE 1. Point my mouse cursor over any of the open windows in the Plasma task manager. OBSERVED RESULT There are no window previews EXPECTED RESULT Window previews are displayed, like in the X11 session SOFTWARE/OS VERSIONS Operating System: openSUSE Leap 15.4 KDE Plasma Version: 5.25.90 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.5 Kernel Version: 5.14.21-150400.24.21-default (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i5-10210U CPU @ 1.60GHz Graphics Processor: Mesa Intel® UHD Graphics ADDITIONAL INFORMATION Normally window previews are configurable with a combobox in System Settings > Display and Monitor > Compositor, but it's not there for me in Wayland.
Does screencasting work in obs-studio?
No, it seems like that doesn't work either :( I get the dialogs to choose a window or a screen, and they have correct items, but then there's no image from them displayed in OBS.
Can you maybe discuss this with your distribution? This is definitely meant to work with your hardware and setup. Something you can try as well is to run plasmashell or "plasmawindowed org.kde.plasma.taskmanager" from a terminal and see if you get debug information. Especially when it comes to pipewire. Logs coming from kwin_wayland would also be useful. You can generally find them in ~/.local/share/sddm/wayland-session.log
This points to a distro PipeWire misconfiguration, yeah. That needs to be set up properly for both of those things to work.
"plasmawindowed org.kde.plasma.taskmanager" prints the following on task hover: kf.plasma.quick: Couldn't create KWindowShadow for ToolTipDialog(0x55bb06a7bba0) QCoreApplication::postEvent: Unexpected null receiver Afterwards, moving the cursor over other tasks only prints the second line. ~/.local/share/sddm/wayland-session.log contains the same output.
It turns out that I had the `wireplumber` systemd unit disabled for some reason (I normally use Pulseaudio). Enabling it fixed the issue: previews show up with a significant delay, but at least I have them now!
Thanks, good to know.
