The current version of gnome-flashback in the repositories has a bug with taking screenshots to the clipboard using the keyboard shortcut. After using it a couple times, pasting the resulting image no longer works and crashes some targets. At the same time gnome-flashback locks up. More details in the upstream bug report: https://gitlab.gnome.org/GNOME/gnome-flashback/-/issues/50 It was fixed in 3.37.1. This is a feature I use daily, and I can imagine many others do too. gnome-flasback has been flagged outdated for a while now, and it seems the maintainer, Balló György has been inactive for some time. Can we get an update for this package? - Roope Salmi
