One day, Wayland will truly take over the Linux world, but it's not quite there yet with plenty still using X11 due to various problems some of which the new Frog Protocols aim to solve.
Announced by misyl, who does various work for Valve (like Gamescope), it certainly sounds like a good idea to give Wayland Protocols a swift kick to get into gear to improve things for users. Writing on their social media post :
Wayland Protocols has long had a problem with new protocols sitting for months, to years at a time for even basic functionality.
This is hugely problematic when some protocols implement very primitive and basic functionality such as frog-fifo-v1, which is needed for VSync to not cause GPU starvation under Wayland and also fix the dreaded application freezing when windows are occluded with FIFO/VSync enabled.
We need to get protocols into end-users hands quicker! The main reason many users are still using X11 is because of missing functionality that we can be shipping today, but is blocked for one reason or another.
