I want to see either a persistent rectangle box on the edges of the region being recorded (anything outside the box isn’t recorded), or dim the parts of the screen that aren’t being recorded. I looked for screen recorders for hyprland & wlroots and didn’t find any with this functionality. wf-recorder + slurp works for me but I want a boundary visual.
OBS could do that, I suppose. Add a screen capture source, and place a color source behind it sized 10px larger than the screen capture rect. Hit record.
