Bug ID: 496798
Summary: Pipewire/Wayland window sharing does not include
sub-windows
Classification: Plasma
Product: kwin
Version: 6.1.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: sergio.calleg...@gmail.com
Target Milestone: ---
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.
