Qustion: Support for Splitting Application Output Across Multiple Displays in Weston

[Yosuke Nakayama]

Dear Wayland-devel Community,

I am currently exploring the capabilities of Weston, the reference
compositor for Wayland, specifically in the context of an application use
case that I am working on. My goal is to achieve a functionality where the
graphical output of a single application can be divided and displayed
simultaneously across two separate displays. This functionality would
enable part of the application window to be shown on one display and the
rest on another, effectively spanning the application window across
multiple screens.

>From my understanding and current experimentation with Weston, this
particular use case does not seem to be directly supported, but I'm not
sure. Does functionality exist at this time to achieve such a use case?

Thank you for your time and assistance!

Best regards,
