Every time I try use Vivaldi I encounter how incredibly slow the UI is. Are all Vivaldi users running it on specced out desktops? Or is it just ao lineux UI latency issue?
I've switched back and forth between Vivaldi and Firefox on Linux and MacOS for the last decade, and Vivaldi's UI feels much faster. Even on my 5yo laptop or 12yo gaming PC, I haven't noticed any real slowness with the UI, and I'm usually pretty sensitive to that.
Same, even on the absolute highest end machines. It has been a few versions since I've given it a go and I otherwise like it but the perf decline over stock Chromium, sometimes randomly appearing, is what has always steered me away again in the past.
Same experience with UI performance, especially on Linux (Fedora). I went back to Zen Browser because of this, but frankly most browsers are performing worse for me on Linux than on Windows.
I'd guess it's the price for custom UI and customization features they're adding
