Webpages with divs and buttons that hover a consistent space of the screen like taskbars and Reddit's "back to top" button flicker white and jitter around when I try to scroll and I would like to find a quick fix if possible. I am a new user and I've only so far had to touch config settings to fix on hover UI with Twitter. Everything else is default settings and I keep getting forwarded to old bug reports and github pages for web developers when I'm trying to fix it from the user side on multiple common pages like Tumblr and StackOverflow.
