When I'm scrolling with my Mouse (Logitech Wireless Mouse M560) I get stuck sometimes. It works perfectly most of the times but then suddenly just stops to scroll completly and only after a few more "scrollclicks" it will go back to normal. And if thats not even strange enough, it will get stuck again reliably if I scroll back to that same position. The problem seems to be somewhere really deep because I checked the events coming from my mouse, while scrolling and they also resemble that behavior.
I've already tried a bunch of stuff like installing imwheel and running it, overriding the MOUSE_WHEEL_CLICK_ANGLE because I thought it could be the missalignment of that (but it isn't).

I just tested my mouse on another Laptop, I guess this will be a slightly different post now...
