Render example for FF5, Chrome and Opera
The man said opera and chrome are not right.
Because he does update box-shadow property to the newest spec. But chrome and opera doesn't.
Where is the truth? Looks like he's right after reading spec.
The attachment is a link to an image. Could you please attach (not link to) your test case?

Yep. Sorry. I thought tracker will download it.

Test-case for Webkit. I don't know how it can be tested).
Oops. It looks equals but it's because hack.
Diff in spread-radius: -8px for webkit and -12px for gecko.
But for positive numbers: 8px for webkit and 6px for gecko (or 12px for webkit and 8px for gecko).
It's very strange.
That's not only if spread is negative. I'm sure.
I must recalculate spread-radius for pretty now by algo:
If spread > 0 then firefox-spread = spread*3/2;
Elseif spread < 0 then firefox-spread = spread*2/3;
But if FF is doing render as told in spec I could say chrome-and-opera-radius ;-) and could do inversion of calculations.
Box-shadow render with spread-radius == 0 is fine (almost equal). And don't if spread is not eq to zero. Afaik.
I don't get what you're saying. Please just make a simple statement of what you think the bug is.
