Created attachment 135886 [details] Screencast Please see the attached screencast. I've changed the shortcut for Capture Rectangular Region to Shift+Print, then pressed that combo, then Enter to copy the screenshot to clipboard. Two notifications were shown, one with the image, one without. Everything took place on the external monitor connected to my laptop.
I use just 1 screen and I can confirm this behavior when "Copy to clipboard" is enabled in Spectacle settings. Spectacle 21.04.1 on Arch Linux.
