User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0 Build ID: 20130329030352 Steps to reproduce: Having embeded svg images on a SVG, if I'll change the viewbox to go deapth, all embeded images apears fuzzy. Step to reproduce the error: 1.- Go to the follow link: http://jsfiddle.net/davidaco/YMWha/17/ 2.- Click on any button ( test1, test2 test3 ...) each button will change the viewBox value. Using Firefox = 20.0 OS = Ubuntu 12.10 Actual results: Images apears fuzzy Expected results: images should display according the zoom level applied on the viewbox.

I tested it in firefox 19 and it works fine, this error just start when i moved to firefox 20

I don't think this is a duplicate of bug 600207, given that a) this (reportedly) started with Firefox 20 b) The fiddle has SVG content inline in HTML, whereas bug 600207 is about SVG-as-an-image Un-duping.

I get this (huge) regression range. Last good nightly: 2013-01-07 First bad nightly: 2013-01-08 Pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=605ae260b7c8&tochange=dccab70d8554 I tested by hitting "test 1" and "test 2", and "test 3" in the fiddle, and resizing the window / frame to see if I could trigger fuzziness in any of the shapes. In the 1/07 build, I couldn't trigger any fuzziness. In the 1/08 build, I'd see fuzziness in at least one object, and I could trigger fuzziness in other objects depending on the window-size / frame-size.

Pushlog for inbound: http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=f80f9b1e217b&tochange=27ed16bab80f I suspect this change: 546f9f3999d3 Robert O'Callahan — Bug 504071. Allow image drawing to snap to pixel boundaries even if there's scaling, on all platforms. Not only is it faster, it avoids seaming. This is consistent with snapping behavior of other drawing operations. r=joe which could have opened us up to bug 600207 in more situations.

So I think this is a regression from bug 504071, and fixing bug 600207 would likely fix it, so I'm marking as blocking bug 504071 and depending on bug 600207.

(In reply to David from comment #2) > I tested it in firefox 19 and it works fine, this error just start when i > moved to firefox 20 Same here. My blurring started in Firefox 20. Also, My svg was in an img tag.

Seems fixed now (in Nightlies) anyone else agree?

Appears to be fixed, yeah! Likely by bug 600207 (as suggested at the end of comment 5).
