@yaakhan I really like Opera, but this issue still remains. It's easy to reproduce. Just launch and close opera a few times and you will see. It is terrible. I have 6 workspaces, with a lot of tab islands and I cannot afford to spend 30 minutes rebuilding them each time they vanish. I cannot understand how this cannot work fine. This is the only think that keeps me using Vivaldi instead Opera.
