User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0 Build ID: 20150713153304 Steps to reproduce: 1. Open a large image (in both file size and dimensions). 2. When image is still loading, left click once to view it as original size (so scroll bar would appear). 3. Middle click. Now you should be able to scroll with mouse movement. 4. Try to scroll. Actual results: The scrolling is extremely lagging, like, 1fps. After the image loaded, the scroll would act as normal. Expected results: Scrolling shouldn't be lagging. Note: it could also happen on a long web page with lots of images. The image itself doesn't need to be large (it's just easier to reproduce). As long as some image are loading and you're trying to scroll after middle click, this bug happens. No idea what product it should be, correct me if I'm wrong.

Same here, when a page is still loading, scrolling with middle click is very slow. However normal scrolling with wheel is perfectly smooth.
Does the testcase in bug 1190093 comment 6 show the same problem?
(In reply to dolphinling from comment #2) > Does the testcase in bug 1190093 comment 6 show the same problem? Yes, it's the same problem! Bug 1190093 should be dupe of this one.
(In reply to Benjamin Peng from comment #3) > Yes, it's the same problem! Bug 1190093 should be dupe of this one. Then this bug should be renamed, because it's not just images loading that causes it, but page loading (while loading spinner is in a tab title, to be precise).

Or just mark this one as dupe of another one, don't really care which one is "parent" as soon as dev would work on it :) (guess not, yet)
