This regression seems very minor. We should try to fix it it nightly. I don't want to track this for 43, but if anyone comes up with a low risk fix, please request uplift to aurora.

[:Paolo Amadini]

Most likely a layout or rendering issue. If it's deterministic, it could help if it can be bisected to a specific bug. It's probably a useful thing to do since it might affect other places as well.

While this is a valid issue, I do not think this is critical enough to be tracked and called release blocking. If we do get a fix in time and it's deemed safe, I would be happy to uplift to Aurora44 or Beta44.

Downloads Panel was re-worked since this issue was filled, there are no artifacts on latest Firefox versions, so I'm closing this issue as RWFM.
