- Videos are jerky compared to Chrome. It doesn't matter if hardware acceleration is on or off, and it's at least on macOs and Windows.
- Scrolling is either slow (if hardware acceleration is off) or shows a blank page as you scroll (if hardware acceleration is on). Chrome works fine with hardware acceleration.
- Caching is weird. Often it would show me an old version of a page, and I have to refresh to get the latest version. For example at some point it shown me a version of a Docker Hub page that was 2 months old. The same often happens on GitHub too (I think it has something to do with caching pages that are fetched via JS). Happens on both mobile and desktop. Never seen this problem on Chrome.
As a result I just went back to Chrome. I don't like the tracking and all, but at the end of the day I need basic features like loading pages, playing videos or scrolling to work. In fact, I'm surprised they don't simply try to use Chromimum more closely - they probably add a layer of "optimisations" which only creates more bugs than it's worth.
