Scrolling through web pages is not functioning

I can no longer utilize the keyboard to scroll through web pages, including this “create topic” template.

When I use the keyboard arrows to scroll up and down any web page, it jumps from one point to another, in the same fashion as tab does on a Word document. This does not occur on any other browser ( yes, I’ve checked) nor is my external mouse affected (I use a laptop).

It’s been going on for at least the past 24 hours and did not occur at all prior to last Brave update.

I use Windows 10

My only only means of scrolling a page are an external mouse or click and hold the scroll bar on the right side of the web pages.
