1195574 - [Mac] SVG text not rendered correctly in Firefox 40 + Mac OS/X

Status: RESOLVED WORKSFORME

(Core :: SVG, defect)

Description

[pcloutier]

Attachment: Firefox OS-X.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150807085045

Steps to reproduce:

My application generates SVG files. Please display the following file in Firefox 40 on a Mac OS/X:

Actual results:

The HTML displays correctly in Firefox 40 on Windows 7, but parts of it are garbled on OS/X.


Expected results:

It should display the same on OS/X as it displays on Windows. 

BTW Safari, Chrome + OS/X and Chrome + Windows display it correctly, as does IE.

Yikes! That looks bad -- thanks for filing. I can't reproduce on Linux, so it sounds like this is Mac-only.

Adding "regressionrange-wanted" -- hopefully someone with Mac OS can confirm the bug & track down a regression range using the "mozregression" tool.

So it regressed with the enabling of SVG text frames.

There's a second regression on the Mac that co-locates the oversized text glyphs. I'll try to track that down too.

Glyph co-location regression range is http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=f8a08d0a1b2a&tochange=17a47dcef75d

which suggests bug 569722

(Shot in the dark: does this only affect Mac with high-DPI (retina) displays?  If so, that might be a hint at why the text is being over-sized.)

Comment 6

[Robert Longson [:longsonr]]

My Mac is not high-DPI. I think it's something to do with the font getting too small. I also think the change by bug 569722 is OK, it's calculating the right offsets but then displaying all the letters too big.

Not a recent regression.

Seems OK now.
