        OS/Version: Windows 2000
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P2

Right now the tiling implementation on Qt WebKit2 still stutters a bit.
There are several steps that could be taken to rectify:
1. reduce number of allocations/deallocations
2. Move to live textures, to avoid uploads
3. Optimize painting into update-chunks by painting with one go to adjacent tiles.
