Hi Adam, Not sure if this helps....
I used QtWebkit2.2 + Qt4.8 on Linux and found severe drop in render performance, when compared to Qt4.7(internal QtWebkit) I am not sure if it was due to some texture mapper / rendering changes that were being refactored soon after 4.8 release. Some time during this texture mapper would work only for OpenGL cases but not Linux/DFB.; but later i guess texture mapper became more generic to use 2D hardware blitter (DFB) as well So upgrading QtWebkit from webkit.org trunk with texture-mapper enabled by default solved my issue (but still i had to enforce a translate3d(0) by force on the body) On Thu, Mar 22, 2012 at 10:16 AM, Coda Highland <[email protected]> wrote: > I'm on Mac (Snow Leopard), and building 32-bit (Carbon, of course) because > of other dependencies. > > Back in Qt 4.7 (specifically, on August 14th, 2011), I had built the > QtWebKit 2.2 branch from trunk in order to get some features I needed for > my application. > > Today I got tired of dealing with the broken inspector and decided to > update to 4.8.0.
