> That is complete BS. The application doesn't talk to the graphics hardware alone and then just copy a bitmap into a Wayland buffer. You don't just magically talk to the GPU. There is this little problem called 'security', 'multiprocessing' and 'multiuser' in between.

This is literally what DRM/DRI is for... which is not Wayland.

If you think the display server should handle applications using the GPU, then even Xorg dropped this approach.
