SUMMARY

I'm using plasma 6.3.6 patched with [this commit][1], and xdg-desktop-portal-kde is patched with [this commit][2] so that I can create a virtual monitor with kwin_wayland launched with the `--virtual` flag.

[1]: https://invent.kde.org/plasma/kwin/-/merge_requests/8472
[2]: https://github.com/KDE/xdg-desktop-portal-kde/commit/8def3b7956d5c544764d4c53a3e848cb86ca26b9

However, it seems when starting the PipeWire stream, I must use a resolution of 1920x1080. Otherwise I won't get any frames. If I try to re-negotiate with a different resolution, the screen will freeze and the PipeWire stream will no longer be usable. This issue only reproduces on KDE and doesn't reproduce on GNOME.

The renegotiation code can be found [here](https://source.chromium.org/chromium/chromium/src/+/main:third_party/webrtc/modules/desktop_capture/linux/wayland/shared_screencast_stream.cc;l=411;drc=9d5809a28521f1c6b09360e45b0bf7e1e7784214).

STEPS TO REPRODUCE
1. Create an [XDG RemoteDesktop session](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.RemoteDesktop.html#org-freedesktop-portal-remotedesktop-createsession)
2. Configure it to use the `VIRTUAL` source with [ScreenCast.SelectSources](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.ScreenCast.html#org-freedesktop-portal-screencast-selectsources)
3. [Start the session](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.RemoteDesktop.html#org-freedesktop-portal-remotedesktop-start) and grab the PipeWire nodes
4. Connect to the PipeWire stream with a resolution of 2560x1440, observe
5. Now destroy everything and redo steps 1-3
6. Connect to the PipeWire stream with a resolution of 1920x1080
7. Renegotiate with a resolution of 2560x1440


OBSERVED RESULT

In steps 4 and 7, no output is received via PipeWire; the stream becomes unusable

EXPECTED RESULT

The virtual monitor should be resized to the specified resolutions, and the stream remains valid

SOFTWARE/OS VERSIONS
(available in the Info Center app, or by running `kinfo` in a terminal window)
Operating System: Linux

ADDITIONAL INFORMATION

Comment 1 Bug Janitor Service 2025-11-26 00:33:40 UTC

Thank you for the bug report!

However Plasma 6.3.6 no longer receives updates or maintenance from KDE; active versions are 6.4 or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need help with Plasma 6.3.6, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.

If you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.

Comment 2 Yuwei Huang 2025-11-26 00:52:42 UTC

I'm fairly sure it will reproduce on the latest version, so I'm changing the version to unspecified. I can't get plasma 6.5+ yet due to dependency issues.

Comment 3 Vlad Zahorodnii 2025-11-26 08:29:34 UTC

At the moment, kwin doesn't support resizing virtual outputs. There were some patches to make kwin resize virtual outputs based on pipewire stream size, we will need to push those patches forward.

Comment 4 David Edmundson 2025-11-26 08:46:24 UTC

Relevant MR: https://invent.kde.org/plasma/kwin/-/merge_requests/7932

I'm happy to move that forward, I don't believe the kwin side is blocked on anything. It was just draft because our client side stuff hadn't landed.

Comment 5 David Edmundson 2025-11-26 08:47:53 UTC

Can you give me steps on how to test with Chrome?

Comment 6 Yuwei Huang 2025-11-27 08:56:18 UTC

This is still in development, and FWIW the code will be in the Chrome Remote Desktop host binary instead of the Chrome browser, so unfortunately you can't test it right now. I checked the WebRTC [ScreencastPortal] and it doesn't seem to support the `VIRTUAL` source type.

If you happen to have a Chromium checkout and you know how to build stuff in Chromium, then I can give you some minimal reproducible code, or you could give you a binary, if you are comfortable with that. 

I'll try to patch your MR and see if that works. Thanks!

Comment 7 Yuwei Huang 2025-11-28 01:56:36 UTC

I tried patching your MR, but it's giving some error and the stream still crashes:
