I have noticed that both on Windows and Linux, Brave is scrolling much slower than other browsers. It can be a deal-breaker for a lot of people who are trying it out for the first time. I have seen a couple complaints about it without answer.
A quick fix that worked for me is to install an extension that increases the scroll speed. I had success with this one, although others may work too:
At 1.5 scroll speed it feels snappy (as it should by default in my humble opinion).
