Viseur

Customizable crosshair overlay that stays visible above fullscreen games and videos. Cross, dot and circle shapes with color, opacity and outline, multiple profiles, keyboard shortcuts, a temporary profile while a shortcut or the right mouse button is held (or toggled), and a panel menu. While the crosshair is shown, fullscreen direct scanout is disabled so the overlay can be drawn; hiding it restores direct scanout.
