The ongoing work for native Wine Wayland support
While most X.Org Developers Conference talks are around graphics drivers / infrastructure work itself, one of the other interesting XDC 2023 talks was Alexandros Frantzis around the ongoing work of providing a native Wine Wayland driver so that this open-source project can interact directly with Wayland and so Windows games/applications running under Linux will no longer need to go through XWayland.
The entire presentation is available on YouTube.
