Summary REGRESSION (r77034-r77220): CSS box-shadow no longer renders on PowerPC

Viewing the gallery at this link is missing the box-shadow or -webkit-box-shadow rendering that existed in previous versions both in an off state and rollover state. See attached picture for how it should look.

Same problem on this site: http://www.realtybymonica.com/ 3 boxes vertically going down the page on the right should have drop shadows.

I cannot reproduce with a local debug build of r79659, so probably Leopard-only.

Kevin: can you try this on 10.6?

(In reply to comment #6) > Kevin: can you try this on 10.6? I can't directly (PPC only here), but I'll have a friend of mine check a webkit build on Friday under 10.6.

(In reply to comment #6) > Kevin: can you try this on 10.6? Just had it checked with the latest nightly and it looks fine in Snow Leopard.

Looks fine on Leopard, on intel. Maybe PPC-only?

Any further thoughts on this. I guess it could be PPC only, but it used to work.

Comment 11 2011-03-22 20:44:37 PDT
Yeah, it's PPC-only.

In case it helps, text-shadow appears to be working while box-shadow still hasn't worked for 2 months.

Martin, do you remember why the endianness check was necessary?

(In reply to comment #14) > Martin, do you remember why the endianness check was necessary? It will be necessary for ContextShadow, that blurs the ImageBuffer bits directly, if your platform stores pixels in an endian-sensitive way.
