Description kangax 2012-01-17 17:02:05 PST 
I'm attaching a test case that shows webkit cutting off text with remote font applied to it. It seems like the issue happens when these 3 conditions are satisfied:

1) text uses remote font
2) text (or its ancestor) has certain padding and margin (in this case parent element has negative margin)
3) element rendering is hardware-accelerated (i.e. has "-webkit-transform: translate3d(0, 0, 0);" applied to it)

Removing either one of them makes the issue disappear. Note that you might need to full-reload the page to see the cutoff. I'm guessing that's what makes text rendering happen _before_ font is being downloaded.

This doesn't happen in Firefox (nightly), Opera (next), or Safari (5.1.2; so it almost looks like a regression).

One more thing: selecting text cause cutoff to disappear. So is inspecting it with web inspector. I'm guessing due to reflow.

I can’t reproduce this in TOT. Can you?
