I have no idea what this is, restarting chrome and my machine doesn't fix it, it seems random and it affects things randomly, and goes away randomly.
Notice this issue comes up with I take the macOS screenshot too. I think it must be a bug with Chrome, not sure if it's my laptop or macOS too?
Not sure how to google for this either, it's a big mystery, and makes a lot of pages unusable unless I’m fortunate enough for it to just go away

16" Macbook Pro?
It sounds similar to this (although most users report blue lines, not green).
Does it still happen if you turn off hardware acceleration in Chrome?
