vscode isn't listed in ksmserverrc. We can only restore clients compliant to X Session Management spec. Please report this issue to Visual Studio Code developers.

Thanks it has been reported to the vscode team, they are looking into it.

For what it is worth, KDE already knows all the windows that are open at anyone time and on what desktop. The session management is junk imho, as I have keep filing bugs for every individual window/app. I think KDE need to rethink it's own session management design.

Comment 6 Kai Uwe Broulik 2020-05-24 10:36:38 UTC

Just because we know what window should be placed where does not mean we know how to re-launch the app. That's why the app has to tell us what we need to do to restore it, which VS Code does not appear to do. It's also not our design, it's an (ancient) X protocol.
