The "shouldSync" is not used in current code. I wonder which "shouldSync" affects in code.

I thought you created "shouldSync" for following purpose.
1. WebCore callbacks PageClientQGraphicsWidget::syncLayers() in order to invalidate.
2. Before invalidating WebCore callbacks PageClientQGraphicsWidget::syncLayers() so many times.
3. PageClientQGraphicsWidget should invalidate only one time for all sync requests.

I experienced performance largely increased by this patch in my project based on private SDL port in the following site. In detail, from 3fps to 20fps.

This site requests more than 600 sync requests before invalidating actually.

I'm sorry for my poor English. English is more difficult than C++ to Asian.
