Vivaldi has lazy tabs
Very lazy tabs. [img]http://i62.tinypic.com/2zhm5h3.jpg[/img] When I open link in a new tab I can see this - then it fills the whole tab. I often open links in background tabs and it's frustrating seeing it every time (it only happens on visiting the tab for the first time). Vivaldi is a very lazy browser.
It's an alpha, it will be optimized
First they have to add all the features, then they can fix the bugs, then they can start to optimize the browser and write some documentation
