If you install uBlock Origin (from either Firefox or Chrome) and just have it enabled (it doesn't even have to have any filters active; it just has to be there), scrolling with the touchpad doesn't work and trying to use the scroll bar causes the screen to spaz out while not actually scrolling.

Scrolling needs to function correctly with both the scroll bar and the touchpad.

    Scrolling works fine for me with uBO/YouTube but I have occasional spaz outs very similar to this just by moving the window while a video is paused

    Still investigating
