794098 - SVG maps no longer works on Firefox 15

Status: VERIFIED FIXED

(Core :: SVG, defect)

Description

[INGV Milano]

Attachment: firefox_chrome_render.jpg

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1
Build ID: 20120905151427

Steps to reproduce:

We currently use HTML + SVG (with ECMAscript) to produce some geographic maps. An example is available at http://emidius.mi.ingv.it/emilabs/svgmapdemo/.
The maps are projected with UTM (http://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system) with 1 meter = 1 unit in SVG.


Actual results:

Until Firefox version 15 all the maps were correctly rendered as with other browsers supporting SVG (tested with Chrome, Opera and IE9). Starting with Firefox 15 the maps are badly rendered: they are incomplete with some paths not rendered, missing background raster (DEM), missing text for the places... also dragging is not working; sometimes they not load at all. Major number of problems are with the maps surrounding the equator.
All the above features are working with, i.e. Chrome and also with Firefox <= 14.





Expected results:

The maps should be rendered correctly (see attachment) as they are pure SVG and they were working on Firefox <= 14, Chrome etc...

To test: open http://emidius.mi.ingv.it/emilabs/svgmapdemo/ with Firefox 15 and then with Chrome.

We have already tested the last nightly build with the same, bad, results.
The bug is present also on Linux (both i686 and x86_64) and Mac OS X

Jonathan, looks like this has large viewBox co-ordinates so I suspect it is suffering from invalid bounds just like bug 791675

I can reproduce the problem in Firefox13 and later, but not Firefox12.

We confirm that the bug is also reproducible in Firefox 14 and 13, not only from release 15. Sorry for the mistake and thanks again.

FWIW The "this is what I was thinking" patch in bug 791675 fixes this.
