There seems to be a design goal in Wayland to prevent clients from making surfaces that they never map. So it would be better if creation + commit of a surface did the same thing as present. Also this does not break existing clients.<br>

There is nothing special about the first time the surface wants attention (other than historical legacy). The desktop should be allowed to turn this into a notification just like it would on subsequent calls.<br>
</blockquote><div><br></div><div>Agreed. Especially if you start an application, but it's slow to start, and you have typed into the current window or have navigated away from it since, you should get a popup instead of the window immediately mapped. This is known as "focus stealing prevention".<br>

If called twice, or more, the request will send an event to<br>
desktop-shell, so it can display a notification.<br>
</blockquote>
<br></div>
This is not controlled by a count, but by whether a window is already visible or already in the notification state. Clients should be able to send a lot of these in a row. They cannot reliably test if they are invisible and send the request only then, as there is a race condition.<br>

I also think the term "present" is not a great idea. This should be exactly the same as "raise" or "show" or "activate" or any number of other terms, but I have never seen the word "present" used before. I would reuse an existing term. One reason is to prevent somebody else from adding a redundant api for that term, because they did not realize "present" is the thing they are looking for.<br>
</blockquote><div><br>For reference, the name was taken from gtk_window_present. I am fine with alternate names for the request, including "activate". I am not comfortable with "raise" or "show", though, as the request is designed to *present* the surface to the window, whenever possible. This may imply a workspace switch, too. The name "raise" or "show" simply says to me about the stacking order or the mapped state, but this may just be my X11 experience talking.<br>
