790288 - SVG disappears when some elements are far outside the viewbox

Status: RESOLVED FIXED

(Core :: SVG, defect)

Description

Attachment: example.svg

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:15.0) Gecko/20100101 Firefox/15.0.1
Build ID: 20120905151427

Steps to reproduce:

Upgraded from Firefox 14 to 15, then tried to view an SVG document that had worked previously.  I've pared down the document to the bare essentials (attached), with 2 example causes of the issue.  It tries to display 2 elements inside the viewbox, with 2 more elements far outside the viewbox.

If I remove the enclosing <g> element, the problem is gone.  If I remove the out-of-range elements, the problem is gone.  If I move the out-of-range elements 1 coordinate value closer to the viewbox, the problem is gone.  If I change the out-of-range coordinate value to a positive value, the problem is gone.


Actual results:

Nothing is displayed.  With a zooming script in place that manipulates the current transformation matrix on the outermost <g> element, the circles inside the original viewbox will appear if I zoom out far enough.


Expected results:

All elements inside the viewbox should be displayed.  Out-of-range elements should not affect this.

Forgot to mention: If I open the Firebug frame, the missing elements are displayed, as they should be.

Does this work if you try it on a nightly? It does work for me on Windows?

Does it work if you run in safe mode?

I'm able to reproduce the issue.
When my Firefox window is maximized, I can't see the SVG (two vertical black circles).
If I reduce the window, the SVG appears.

It's the sort of thing that bug 791675 should have fixed.

Cool. Closing as fixed by bug 791675 then.

The first release to have this fix will be Firefox 19.
