On KDE the maximization doesn't work properly anyways, as the cursor still allows resizing of the window even when it's maximized via the maximize button.

Sounds like an argument in favour of server-side decorations to me. (Personally, I'd rather have that properly implemented as an option, mainly for consistency reasons.)

Dropping a note on this to say I've been testing Pop_OS and it still doesn't maximise the window on double click.

My workaround for this issue has been to force enable decorations with devilspie2 using the following script:

if (get_class_instance_name() == "steamwebhelper") then
    decorate_window();
end

On Plasma one can set up a window rule to achieve the same result.

While this does end up with duplicate window controls (the Steam and the DE ones), since mine show on the left side it doesn't look as bad, and is also more convenient since steam doesn't follow the system settings anyway.

Hi, the problem is still relevant and very annoying. Fedora 44, the latest GNOME, is still affected.

Nothing extracted yet.
