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

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

99.99% chance it's that, as I've had similar issues in the past due to DBus's fragility in dev sessions.

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!
