Qt5 does have GLES acceleation. It can be easily turned on and off, but it's 
required for QtWebkit, IIRC. Why are you saying there's no SGX acceleration?

As of the question - I'm fine disabling sgx MACHINE_FEATURE for now. Let's 
talk to the graphics team to see if/when it will be aligned/resolved.
