You can't screenshot a context menu. Xfce-screenshooter doesn't open. I'm currently on ArchLinux with the 4.20.5 Linux-Zen kernel and the GNOME Shell 3.30.2 How to replicate the bug: - sleep 5 && xfce4-screenshooter -r - Open a context menu (For example right click in Chromium) - Wait till the sleep runs out The only errors (warnings) I get are: ** (xfce4-screenshooter:24193): WARNING **: 20:12:13.216: Failed to grab keyboard Or ** (xfce4-screenshooter:24261): WARNING **: 20:12:37.414: Failed to grab pointer If you need any further information, please contact me. Regards.
See: https://bugzilla.xfce.org/show_bug.cgi?id=12323#c9 Instead of sleep, try: xfce4-screenshooter -d 5 -r This way you can select a region where the menu will appear after the 5 seconds delay.
