Tab Bar is borken
It looks weird... :-$ Attachments: [img]https://forum.vivaldi.net/uploads/attachments/39525/tab_bar.jpg[/img]
That's a feature of the browser. You can resize the tab bar with the mouse cursor. Hover over the bar just below the tab bar and above the address bar, then click and drag up or down. Double clicking has the same affect.
Included attached screenshot to illustrate.
The part under the tab is just a tiny piece of a tab thumbnail. Drag up to hide it again, drag down to show more.
