@kde I’ve been using Global Menu for a while, but since it is less and less supported, I’ve finally removed the widget.
However, I did not get the local menu back! Now all my KDE apps have no menu at all.
I thought that restarting the session would fix it, but it did not help. Anybody has any hint on how to fix this?
You are right. I don’t use vivaldi, but gave it a try and sure enough it didn’t display. Well I would say most chromium browsers and electron apps do then.
