Status: RESOLVED WORKSFORME

(Core :: SVG, defect)

Description

[thomas.papin]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.127 Safari/533.4
Build Identifier: Firefox 3.6.8 Ubuntu

I created a SVG that is using a pattern image. When I load it into firefox, the system is freezing. Using Top command, I can see that Xorg is using 100 % of CPU, if I kill the firefox process, I wait 2 min, the system is back.

The same SVG can be load correctly on Google Chrome and Inkscape.

Reproducible: Always

Steps to Reproduce:
1. Just open http://www.joomprod.com/map8.svg
Actual Results:  
System Freeze

Expected Results:  
Display the SVG

What driver are you using?  This certainly sounds like a driver bug (Chrome does its rendering client-side instead of offloading to the X server, so doesn't hit driver bugs as much at the expense of slower rendering with decent drivers).

I am using another PC (no more at work)
But same problem here with Ubuntu 10.4 Firefox 3.6.8
Here I am using NVIDIA Drivers: 195.36.24

Same problem also on WINDOWS VISTA:
Mozilla/5.0 (Windows; U; Windows NT 6.0; fr; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 ( .NET CLR 3.5.30729; .NET4.0C)

In fact, my description is not perfect. It's not freezing.

On Linux: All the system become slow, I cannot do anything,(even if I wait a long time). The only way, to restore is to used another computer with ssh to kill the firefox process. With top command I can see X server : 100% CPU

On Windows: Only the firefox application crashes.

I think the error is linked to my "pattern" in the SVG. Maybe a special case, make an exception or infinite loop in the system

Ah, thanks.  Doesn't sound like an xorg-specific issue, then.  Would be good to get a reduced testcase (sounds like should be doable on windows).  Martijn, do you have time for that?

Just another information
In my SVG, if you remove the width and height properties of the <pattern> tag the SVG is loaded without firefox crash.

If you check also the viewbox of the SVG (xmin,ymin,width,height), you will see that the width and height is small about <2.

And my pattern width is about 50.

I will try tomorrow at work to isolate the issue in a small SVG. Even if I found another way to write the SVG without bug. :)

Are you still able to see this on the latest trunk?

Thomas, if you still have the file, could you attach it to this bug using the "Add an attachment" link?

Hello. Any news?

Ok, I found the file again:

Be careful, this will freeze your linux system.
It's working great on chrome
It's still freezing using Firefox 6.0.1

Thanks, Thomas.
Confirmed on Debian GNU/Linux x86_64 with
Firefox 7.0b2
Mozilla/5.0 (X11; Linux x86_64; rv:9.0a1) Gecko/20110901 Firefox/9.0a1

It also makes X.Org use a lot of RAM.

Adding "image/png" to the data: URLs does not change it.

Possibly a dupe of bug 465087.

Comment 18

[Jonathan Watt [:jwatt]]

Seems to work okay since at least Firefox 19. There was a marked improvement between 17 and 19. I didn't test further (or builds prior to 17) so I don't know exactly what fixed this.
