SUMMARY When sharing a window using pipewire window sharing in a plasma wayland session, sub windows cannot be shared STEPS TO REPRODUCE 1. Open an application that creates a window and that under certain circumstances can create other windows (dialogs, etc.). - For instance I see the issue with LTSPICE, that is an application running under wine that I often use for education with window sharing to OBS. This application opens dialogs to add components to a schematic, to show measurements made on waveforms using cursors and so on. 2. Open an application supporting screen sharing, for instance, OBS Studio 3. Ask the latter application to "capture" some window. OBSERVED RESULT You will notice that capturing some window content normally works. However, when the application opens another window, this is not shared. Furthermore, if you try to activate window sharing when this other window is open, this window is not proposed for window sharing. The only way to share it is to share the entire screen. EXPECTED RESULT There should be an "application sharing", supporting the sharing of all the windows corresponding to an application and in window sharing it should be possible to select any window, including those corresponding to dialogs.
