It has the same affect on Safari on the mac too.
Safari 4 on Mac works fine for me (i.e. it correctly implements the -webkit-backface-visibility), as expected given 
that Apple itself provides the sample.

This bug still exists even in the latest Chrome developer build (5.0.342.9).

It's really affecting a page we're working on, and since we can't test around it — webkitBackfaceVisibility behaves 
totally normal and returns the right values, just doesn't render properly — it's driving us nuts. :)
(And in regards to pkinlan comments -- this bug definitely does _not_ appear in Safari.)

That screenshot was from safari.. You must be on a slightly different version as it definatly appears and it 
also appears on the cube demos on the web.

It indicates it is likely a webkit issue rather than a chrome only issue.

This works great in Safari 4.0.5 (6531.22.7) — Snow Leopard — but it does not seem to work in Safari 4.0.5 
(5531.22.7) — Leopard.

That at least means it has been fixed, but I admit I don't know how often Chrome syncs up with WebKit...?!

Cool - good investigation.  I will speak internally to see if I can see what is happening. (I need the bug fixed).

Just to clarify - I am on Leopard.
I filed a bug with Apple regarding the Leopard / Snow Leopard discrepancy.

They said: "Backface-visibility is only supported when ACCELERATED_COMPOSITING is enabled,
and in that situation it works. ACCELERATED_COMPOSITING is disabled on Leopard, depending on the 
QuickTime version."

pkinlan, I don't know if this helps you, but it's probably a good place to start:


Webkit Bug Reference:
This appears to be working in the latest builds of Chromium if you are on Snow Leopard and start Chromium with --enable-accelerated-compositing

This appears to be happening again in 18.0.1025.39 beta chrome
Still an issue in 18.0.1025.168 but only on certain computers. Sporadic. Adding --enable-accelerated-compositing is not an acceptable solution, as web developers working on major client-facing sites can't expect users to run Chrome that way.

This is definitely not fixed
Version 20.0.1132.57 on a mac
Google Chrome is up to date.

needed to use threaded compositing & accelerated animation in chrome://flags/

Version 22.0.1229.79 on Win7: this is not fixed.

I am seeing *some* of the content through the back face. Giving the element opacity: 0.99 fixes the problem (i.e. none of the content bleeds through the back face any more).
