Bug 498476

SUMMARY

When you use `xdg-desktop-portal` to share the screen, you are given the option to activate a `New Virtual Output` to be shared. This can be extra useful to record the behavior of some application, or cast it while maintaining your regular screen usable. However, there is an important limitation in that you cannot select the new virtual output resolution. That appears to be always 1920x1080. Even if you go the the KDE settings -> display and you select that display, that single resolution appears to be available. In some cases this is rather limiting.


STEPS TO REPRODUCE
1. Launch `obs` (obs studio)
2. Add a new source, select screen capture (pipewire) as the source type
3. See the *screen sharing* window from the kde xdg-desktop-portal backend
4. Select New Virtual Output

OBSERVED RESULT

A new virtual output is activated only capable of the 1920x1080 resolution.

EXPECTED RESULT

Either the resolution is asked, or it should be possible to change it with the display settings.

ADDITIONAL INFORMATION
