Description alessandro.portale 2011-04-22 06:51:53 PDT 
If I define opacity and -webkit-transform in the "@-webkit-keyframes" of an animation, the opacity dos not change/animate. Only the transform happens.
This does only happen if I use QGraphicsWebView. If I use the good old QWebView, everything works well as expected.

Reproducable at least on Windows and Symbian^3. Tested with the Qt/QtWebkit packages that come with Qt SDK 1.1rc.

I can reproduce with trunk.

This is related to accelerated compositing. When disabled, the animation is rendered correctly.

Taking and blocking QtWebKit-2.2 on this. QGraphicsWebView is currently broken in the default config, which is pretty uncool.
