Hi list,

During the vUDS session in which we discussed plans for the browser, one 
of the issues that was mentioned is a supposed regression in the way 
pages are progressively rendered while being loaded.

It seems that when we were using Qt5 beta1, pages started to display 
faster than they do now (we’re using Qt 5.0 now, and will upgrade to 
5.0.1 soon). At the time the browser used in the ubuntu-touch image was 
snowshoe, but we’ve recompiled it against Qt 5.0 and we’re observing the 
same issue as with our custom browser. We haven’t been able to quantify 
the issue.

It was suggested that maybe progressive rendering was turned off, or 
delayed, but in my tests I’m seeing the pages start rendering before 
they’re fully loaded, so this seems to be working. Could it be that a 
change in Qt/QtWebKit between the beta1 and 5.0 final releases affected 
the timing of when pages start rendering?

Speed is mostly about perception, so if we can somehow make the loading 
of pages feel faster, it’s a clear gain from a UX standpoint.

Any suggestions/pointers welcome!

Cheers,

 Olivier
