SUMMARY With Spectacle 21.08.2 in Wayland, I can capture the window under cursor via the GUI but cannot do so in background mode. spectacle -bn -u -o $HOME/Pictures/"$(date +%Y%m%d-%H%M%S)".jpg does nothing (bound to Meta+Ctrl+U). spectacle -bn -r -o $HOME/Pictures/"$(date +%Y%m%d-%H%M%S)".jpg works (bound to Meta+Ctrl+R). spectacle -bn -f -o $HOME/Pictures/"$(date +%Y%m%d-%H%M%S)".jpg works (bound to Meta+Ctrl+F). spectacle -bn -d 10000 -o $HOME/Pictures/"$(date +%Y%m%d-%H%M%S)".jpg works (bound to Meta+Ctrl+D). EXPECTED RESULT Using "-u" should work in background mode. Or maybe "spectacle --help" should be modified to indicate which options won't work in Wayland.
