Text also has display issues (missing or truncated letters. There are no issues on same animation with css3 effects removed. Expected results: Images and text should render properly.

Can you provide a reduced Testcase showing the Issue and attach it to this Report or give a Link to a public URL?

You can now play a bit with that demo (click "move nav right" "move nav left" and notice display issues. I just updated it, then you can see how it acts well with Webkit (chrome, safari, etc…)

Demo updated again with both cases : images and text display issues + only text display issues. As a final note, everything ran fine with FF13.

I can repro this with HWA disabled only (Win 7 x64). It's fixed on Aurora/Nightly.

Ok, but i'm under OSX (10.6.8, and same issues under Lion 10.7.3), so how to know if it's really fixed ? :) Is there any related resolved tickets on bugzilla ?

According to comment #5, your bug is likely a dupe of bug 775163 (see comment https://bugzilla.mozilla.org/show_bug.cgi?id=775163#c3) that has been fixed by bug 772079. It's fixed in Aurora/Nightly, not in Beta.

Yep, it seems a duplicate of 775163, thx for info ;)
