Attachment: LinuxArtifact.jpg

Reproducible on: 
Mozilla/5.0 (X11; Linux i686; rv:31.0) Gecko/20100101 Firefox/31.0 (20140429030201) - latest Aurora
Mozilla/5.0 (X11; Linux i686; rv:32.0) Gecko/20100101 Firefox/32.0 (20140429030201) - latest Nightly

Steps to reproduce:
1. Open Firefox
2. Open a new tab (Ctrl/Cmd+T; about:newtab; "+"button)
3. Select Bing or Amazon search engines from the search toolbar
4. The selected search engine icon is displayed in front of the search field - click on it twice (to open the search engine list and to close it)

Actual result:
A visual artifact is shortly displayed on the screen when closing the list

Expected result:
The list is hidden without flaws.

Notes: 1. Not reproducible on Mac OS 10.8.5 and Windows 8.1 64-bit.
2. The issue wasn't reproducible on try builds from  2014-04-08: https://bugzilla.mozilla.org/show_bug.cgi?id=962490#c41 so it's a recent regression.

It's an arrowpanel animation problem.  Neil, have you seen this?  The only similar bug I found was bug 994562, but it's not the same.

It's probably related through. We plan on disabling the animation on Linux in bug 1001234 which will mitigate the issue in the short term.
