SUMMARY Triggering the shortcut to Capture Active Window doesn't work for me on Wayland. If spectacle is currently running, it will report that the capture couldn't be made. If is not open nothing happens. Shortcuts for other modes do work: Rectangular Region and Screen Capture. Capture window under mouse does work when launched from spectacle. STEPS TO REPRODUCE & OBSERVED RESULT (Spectacle is not running) A1. Press the shortcut for "Capture Active Window" (default Meta+PrintScr) A2. Nothing happens (Spectacle is running) B1. Open Spectacle B2. Press the shortcut for "Capture Active Window" (default Meta+PrintScr) B3. Inline message showing the capture couldn't be made EXPECTED RESULT The active window is captured SOFTWARE/OS VERSIONS Operating System: Kubuntu 22.04 KDE Plasma Version: 5.24.80 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 Kernel Version: 5.13.0-30-generic (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8565U CPU @ 1.80GHz Memory: 15.3 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION In case this is related, PrintScr shortcut (for just opening spectacle) hasn't also been working for me for a while, both on X11 or Wayland, so it might be some problem with dev-session DBus shennanigans

If it works when you right-click on Spectacle's icon and choose "Capture active window", then it's the DBus issue, not a problem in Spectacle.

Ok, confirmed this is opening right... It would be nice to have a dev-session issues section :) Closing, thanks!
