In Firefox however, the letter are not painted properly (seen here: http://www.flickr.com/photos/cadecairos/4996818030 ). In both cases I typed the letters A-Z in alphabetical order on the top of the screen. It's probably unrelated, but if you look at the doodling in each case you'll see Firefox also has some trouble there as well. (separate bug?) Reproducible: Always

So what are the steps to reproduce? Just load the thing and wait for the postcard stuff to appear? Is this a regression?
From the screenshots it looks like a disagreement about when new paths are supposed to begin, and/or behavior of lineTo and friends without an initial point in a new path. But that's just a guess; would need a testcase to play with/examine.

(In reply to comment #1) > So what are the steps to reproduce?

I tried making a locally playable version of the postcard editor but wasn't very successful. I'm still hacking at it though.

I reduced this to the point that I can just draw the letter A--it's still a lot of code the way they do it. I see two different issues in 3.6 vs. trunk. In 3.6 I get the basic shape of the A, but no branching. On trunk, I get the following error: Error: this.branches[i] is undefined Source File: file:///Users/dave/tmp/wilderness/index.html Line: 667 I wonder if the latter is bug 595963? Chrome doesn't lose array elements.
I think it's the opposite. Firefox is render things correctly while Chrome/Windows/Linux is not. Unfortunately most of the people that worked on that part were using MacOS and never realised. To sum it up, Chrome/MacOS (CoreGraphics) and Firefox seem to be rendering that fine. I think it's a problem of Skia drawing lines with very low opacity values.

I don't think that's what I'm seeing. Firefox doesn't draw branches at all for me, and I'm on Mac, the possible js bug notwithstanding.

Here's what I see on Mac, 10.6, with Firefox 3.6, Minefield nightly, Chrome, Safari.
Does that happen only with the letters? Or also when drawing using the mouse?

That works for me, both on trunk and 3.6.
Yeah, this is bug 595963. Thanks for helping narrow it down.

This bug was marked as a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=595963 , which has since been marked as resolved, but I still see the letters being drawn incorrectly on Firefox 4. Is anyone else seeing this as well?

With regards to last comment. Looked up this bug 'cause I was hoping it had been fixed. And happy to say it does indeed work fine. Firefox 8.0a1 nightly 2011-07-06 (Linux x86_64) Try using a more recent version?
