    Strange scroll speed issues with touchpad

    I have Lenovo IdeaPad z510 laptop with windows 10 (upgraded from 8.1).
    For a few months (or more?) I have a problem with my touchpad:

    In some situations it doesn't work at all. Sometimes it works just fine. And sometimes it's so fast that I can't control what it's doing. And it's not always the same speed. And sometimes the faster I try to scroll the slower it actually goes.

    Note: I use 2-finger scroll.

    Google Chrome:
    It seems to work just fine, but sometimes (witout any obvious pattern other than that when it happens - it happend everytime I try) when the window is out of focus or when I scroll with just the right speed - it goes uncontrollably fast. And when it does that - the faster I try to scroll the slower it goes (I will later describe it as faster=slower)

    Netbeans/all java programs:
    Works only when the window is not in focus. And sometimes too fast. And faster=slower

    Doesn't work at all

    Windows CMD window:
    Way too fast to do anything. Even with 10000 lines (max) it's so fast that I can't measure the faster=slower effect.

    Explorer.exe, Edge browser:
    These work fine

    What may be possibly wrong and how to fix it!?

    I'm 100% sure it's fixable because it works correctly on linux.

    These issues already went away for me, not sure why and when. I too rarely use windows. There are still some programs that act weirdly, but it's no longer as bad.

    When I think fixed it was removing drivers for the touchpad and then let windows 10 find and install drivers by itself.
