Now, opening 10 tabs or more is bellow the 0.03%. I know now why it is calling windowUrlFromMetadata. Because unlike firefox and chromium, with sub processes using the same executable but with parameters, the vivaldi sub processes are called vivaldi-bin, and there is no .desktop file for that executable name. As soon as I've manually created a .desktop file for vivaldi-bin, plasmashell cpu became normal without the patch. With the patch, there is no need for the .desktop file.
