I'm not able to reproduce this. I tested using the latest nightly, on both Windows 10 and Linux (including with scrollbar buttons enabled).

I was able to repro on Windows 10 when I tried it.

I'm guessing invalidation related? So switching tabs and back should fix the problem?

(In reply to Timothy Nikkel (:tnikkel) from comment #3) > I'm guessing invalidation related? So switching tabs and back should fix the > problem? I think it's invaldation-related, yes. In my case even just letting go of the scrollbar thumb fixes it. I sometimes see multiple lines instead of just one, but they're always pretty close to the "up arrow" button.

Tested this issue on Mac, Windows, and Ubuntu with FF Nightly 56.0a1(2017-07-12) and FF beta 55.0b8 and I can't reproduce it. I will mark as Resolved WFM. Please reopen it if you are still able to reproduce it.
