This is a metabug to track Deferred Rendering in GTK+ port.
The purpose of Deferred Rendering is to perform rasterization on a dedicated thread to improve performance.
Current implementation of WebKit burdens the main thread with many jobs including layout, JavaScript execution, painting, and other heavy jobs. By performing rasterization on a separate thread, we can reduce the responsibilities of the main thread and bring a noticeable performance improvement.
For details, refer to the following design document:
