I am trying to get a screen recording of an issue in nautilus progress popover.
via Gnome Shell screenshot option
But, when I press the top right system menu in Gnome Shell to access the screenshot button, the popover in nautilus disappears.
I did try to set modal / auto-hide property via GTK_DEBUG=interactive, and it works, but I want to know if there is straight forward way to achieve this.
Oh, you’re trying to get to the screenshot button—sorry, I didn’t quite follow that step, and I thought you were using the key combination.
You can use the PrintScreen key to show the screenshot UI, and that won’t close the popup; if your keyboard does not have a PrintScreen key, then you can go in the Settings → Keyboard → Keyboard Shortcuts, select Screenshots, and override the shortcuts there:
