JxBrowser 8.18.3

Delegated screen capturing 

JxBrowser now supports delegated screen capturing. That is the mode where the OS presents a system dialog for the user to choose the capture source, instead of exposing all windows and screens directly to the application.

Delegated capturing is the default mode on Linux/Wayland.
