</div>By the application and the compositor they're designed for having a specific<br>
extension that they use to negotiate the position. The compositor may allow<br>
this extension only to known applications it launches. Or maybe not at all:<br>
the compositor may want to do that only via plugins running on the compositor<br>
itself.<br>
<br>
Either way, as far as I know, the process is not going to be standardised.<br>

<br>
</div>That's expected. Any application knows only about its own windows and never<br>
knows about the global position.<br>

</div>This kind of issue should be solved on the particular use-case, as opposed to<br>
telling the application about its global position. This should be solved for<br>
all kinds of popups, including menus.<br>
