The Best Ubuntu 26 Software Series Part 1: Powerful Wayland screenshot tool – Mark-Shot
mark-shot is a high-performance screenshot and annotation tool built with Qt 6. Originally designed for Wayland compositors such as niri, it now supports standard screenshot and annotation workflows on Linux (X11, GNOME, and wlroots/Wayland desktops) as well as Windows environments.
It captures screen frames instantly and opens an interactive fullscreen overlay, providing region cropping, rich annotation, clipboard copying, saving, and desktop pinning features.
