I'm seeing very dark background color when I hover over some tweets on
https://twitter.com/geekylonglegs/status/1111806913069674496

Not sure what the hell is happening here but it looks awful.
Maybe it's a page issue?

I can reproduce this. Oddly only around that video. Looks like some kind of corruption.

Does it reproduce with "full-page accelerated drawing" disabled?

Looks like Cmd+F with "All caps?" would make it more likely to reproduce. I can reproduce on STP79 as well as Safari 12.1.

This appeared to be fixed now.
