1387692 - Text in svg is not displayed correctly

Status: NEW

(Core :: SVG, defect, P3)

Description

[Pit]

Attachment: Screenshot with 29.5350 and 29.5351

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0
Build ID: 20170628075643

Steps to reproduce:

The bug can be reproduced by this svg-File

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" id="geoView"
 x="0" y="0" width="3840" height="1969" viewBox="0 0 55.8 29.5350" version="1.1" style="text-rendering:auto">
	<g id="5814" prio="140" fill="rgb(0,0,0)" fill-opacity="1" fill-rule="evenodd" stroke="none" stroke-linejoin="round" stroke-linecap="round" stroke-width="1" stroke-miterlimit="3" font-family="Arial, sans-serif" font-weight="bold" font-size="0.3" transform="scale(10)"  onclick="locateMe(evt)">
		<g>
		<a xlink:href="#xxx"><text id="257940" stel_id="257940"  transform="rotate(0 .7401211 .3)"  text-anchor="start"  x=".74"  y=".3" >RDUN : Durmersheim Nord</text></a>
		</g>
	</g>
</svg>



Actual results:

All letters of the text are displayed at the same location. Changing 29.5350 to 29.5351 repairs the display


Expected results:

The text should always be displayed correctly

I can reproduce the issue on Windows and Linux MINT since Firefox25.

Regressed by: 3a23afb038a5	Cameron McCormack — Bug 839955 - Enable new SVG text frames. r=roc

Indeed, Setting svg.text.css-frames.enabled = false fixes the problem on the bad build.

Could you please help me: where do I set svg.text.css-frames.enabled = false? What is the bad build? Should I use an older firefox version to avoid the bug?

Thanks

The preferences has been removed. It is no longer available in recent Firefox.

Because it's a too old version, It is vulnerable and should not be used.

Now I know why I searched without success!

Do you have another idea, how I can correctly display the svg-files that have this problem? They are not so simple as the testfile I submitted. Where is the limit up to which the text is displayed correctly? I found out this 29.5351 only by try and error.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
