[Additional notes]:
- About:support content https://pastebin.com/ThXspxP6
- Setting layout.css.scroll-anchoring.enabled on false makes no difference
- Scrolling inside any of the test cases provided inside the page has no flickering effect on the long page scrollbar
- I could see the same issue, also when involves more than one scrollbar with the following
test case: https://bug1412272.bmoattachments.org/attachment.cgi?id=8925062 (only on the first horizontal scrollbar) - Not reproducible with Chrome on the same machine
- Not reproducible on Win 7 machines with ATI Radeon 3000 and NVIDIA GeForce 21
- Attached a screencast (couldn’t catch the problem with a screen recorder), unfortunately the issue is hard to observe with this video, but it is very prominent on the actual screen

I wasn't able to reproduce this, but based on the symptoms and the fact that it only occurs with some video cards, this is most likely a graphics issue.
