I am trying to achieve what you see in the picture above. I am able to take a screenshot of Synaptic Package Manager using Spectacle without that pop up window circled in red but not with it there.
I am using my keyboard key called Print Screen to take screenshot, pressed once, and saved automatically. Thank you in advance
When trying to capture context menu’s, I generally tend to launch spectacle GUI and set a delay of maybe 6 seconds before executing (generally ‘rectangular’ or ‘Active Window’)
it’s possible using delay and the shortcut keys with spectacle set to always remember the region and to use that last mode.
you might need to take a practice shot (or two) to get the rectangular region set up in advance to capture where the popup will be.
then you trigger spectacle with the shortcut, quickly conjure up the popup during the delay period, and then when the screenshot happens it should capture the popup.
you may need to check the box that says include popups and mouse cursors as well.
