I believe this is because you use the size of the frame's view, which
is 800x800. Maybe use the web page directly? I'm not familiar with
Chromium WebKit API so I have no idea if this would work or not.

Try to use draw filter for Skia. Check the class SkDrawFilter or even
better SkPaintFlagsDrawFilter.
Or even, downscale it yourself with linear interpolation.
