There's a regression, probably since the changes to the build, that makes Qt compile with 3D rendering disabled. 3D rendering should be enabled by default in Qt.
3D rendetering is enabled by default. What kind of regression do you mean? Source/WebCore/features.pri: ... !contains(DEFINES, ENABLE_3D_RENDERING=.): DEFINES += ENABLE_3D_RENDERING=1 ...
