@RmX382 What distro are you using? Can you try disabling hardware acceleration brave://settings/system and see if that effects things?

I am on Ubuntu 20.04.2 LTS. I have tried your solution and it works.

I'm also having a similar issue where touchpad scrolling becomes unstable with a second window open. Disabling hardware acceleration also resolved the issue for me.

The scrolling only happens once the mouse is moved after scrolling. eg: scroll, nothing happens, then move mouse and the windows jumps to where it should've scrolled to.
