I tested this using wlroots with these changes applied: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4509 N.b. there are instructions on how to reply to threads on lore.kernel.org. For the original thread, instructions are on the bottom of this page: https://lore.kernel.org/lkml/20240109181104.1670304-1-an...@yngvason.is/ It's needed for bookkeeping on lore.kernel.org and it's useful for recipients who will otherwise have to search through their email to find the context. Regards, Andri
