User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160107004004

Steps to reproduce:

1) Set background to a url on an input element of type "submit".
2) Set background-position on input:hover.

Actual results:

Background does not change on mouse hover.

If manually setting the element state to :hover in dev tools, the background position only changes if you scroll it off the page.
The background position does change if you click the element.

Expected results:

The position of the background image should change.

The attached test has two inputs: one of type submit that exhibits the problem and one of type text that exhibits the expected behavior.

I was able to replicate the issue in Firefox Developer Edition (45.0a2) and Firefox Nightly (46.0a1) with a new profile but not Firefox 43.0.

jsfiddle matching the attached test:
Works in Fx44b8, not works in 45.0a2 (2016-01-12) & 46.0a1 (2016-01-12).

It seems there are two bug:
1: the button have focus will not get background while mouse out, but the background be restore when focus out.
2: the button lost the background when got focus, not be restore.

Do we need more help on this one? The regression was backed out in bug 1244258. Bug 1201327 is where further work will happen.

OK, thanks for the information.
BTW, unaffected is enough to remove it from our radar (we keep the tracking because knowing that it has been tracked for 45 is an interesting information for us)

Bug 1201327 got backed out on 46, so this is now 46:unaffected.
I've backed out bug 1201327 on Aurora 47, so this bug is only present on Nightly now.
