During November 2025, nvraxn updated the privacyguides/privacyguides.org repository to clarify how Wayland compositors manage screen capture permissions and the security benefits of sandboxed applications. Focusing on Linux desktop environments, nvraxn enhanced the documentation to explain the portal and permission-store workflow, detailing how Flatpak and Snap integrate with Wayland for secure screen capture. The work included concrete examples of dbus calls and described the app identification process using XdpAppInfo, emphasizing the importance of system-level desktop-file entries. Using Markdown and leveraging expertise in Linux, Wayland, and security, nvraxn provided engineers with precise guidance for safer integration with desktop portals.
