Vivaldi 3.6 Introduces Two-Level Tab Stacks

Re:Vivaldi 3.6 Introduces Two-Level Tab Stacks by ajtjp on Thursday January 28, 2021 @08:30PM (#25952425)

I'm curious what area of Vivaldi is perceived as slow. I use Vivaldi at home (on a 9-year-old desktop), and Firefox at work, and the only things that come to mind are tab opening/closing could be better, and some very CSS-heavy animations such as the NYT's map of coronavirus's spread from Wuhan are much better on Gecko than Blink. But day to day, I have no complaints about performance from either.

Then again, I also use uBlock Origin... perhaps Vivaldi is slow without it. I'll also admit that theoretically I'd expect Vivaldi's UI to be slower due to being based on web technologies instead of native, but I can't say I can perceive a difference except in edge cases.

Tab handling was at least x1000 slower than Chrome last time I tested. It got dramatically slower in the last few snapshots and the official 3.6 Stable build.

Its not just tabs, address bar handling is totally broken, opening new tab and starting to type quickly will result in eaten letters. Opening new tab, clicking CTRL-F and starting to type will again open with ~1 second delay and lost letters.

Then we get into broken javascript causality https://jsfiddle.net/rasz_pl/v36nozsw/ open in normal browser and Vivaldi, Vivaldi address bar handling code is overriding scrollTop with delayed location.hash update.
