Enabling the QGLWidget on MacOSX has some rendering and input issues. I'm not sure yet if these are only input event issues or just repainting issues.
This is the command I've tried, but it looks like other pages reproduce the issue too.
bin/QtTestBrowser -graphicsbased -webgl -gl-viewport http://html.adobe.com/webstandards/csscustomfilters/cssfilterlab/
I see the lots of the following messages on the console:
QMacCGContext:: Unsupported painter devtype type 1
QBackingStore::flush() called with non-exposed window, behavior is undefined
