I allways assumed the wayland client allocates the buffers, not > the server. Is that wrong? Hi Gerd, a fly-by comment here: The standard operation mode on Wayland indeed is that the client allocates any pixel buffers. It is not the whole story though. Server allocated buffers passed to a client also exist: - core protocol uses this to pass keymaps to clients - people are not forbidden from writing Wayland extensions that do this for whatever reason The latter server-allocated case could probably be overlooked, but the keymap case not really. Furthermore, copy&paste and drag&drop protocol pass pipe file descriptors via Wayland to establish client-to-client pipes. Thanks, pq
