Firefox 47 does not clear graphics properly in Toolbar

[Wise Melon]

I have found that in Firefox 47 (currently the latest) that when for instance the star animation is playing for the bookmarks button in the Toolbar or when the downloads animation is playing when a download finishes that it leaves some of the graphics behind. This often happens, but not always.

Here are some example screenshots:

And there is nothing seemingly I can do to get rid of these annoying graphics (I have not tried replaying the animations again, but I will update this report when I have tested that).

I am running Ubuntu GNOME 16.04 with GNOME 3.20.

Status changed to 'Confirmed' because the bug affects multiple users.

I have also seen this, specifically the download animation. I just unmaximized and maximized the window again to clear it.

Upstream want me to provide some more information (e.g.: if the issue exists in safe mode and if it exists in the official Mozilla Firefox binary (without any local distro changes)) but due to some other unrelated issue I am having trouble with this. So I was wondering if anybody else could see if they can reply to upstream while I am resolving the issues preventing me from giving this data?

So this is what mine renders like after a download and then hover over a bookmark in the bookmark toolbar.

My upstream bug has been marked as the duplicate of another.

This was fixed in firefox 49.0+build4-0ubuntu1 and the variants for precise, trusty and xenial.

Marking Ubuntu GNOME content as fixed to close.
