> It seems that this is not good idea to move code from ewk_tile_new function to _ewk_view_tiled_render_cb. Initialization of cairo surface should be done only once per tile. Initialization of new cairo surface on every _ewk_view_tiled_render_cb function call seems to be performance lost. Do you have any test result how performance will be changed?

I'm not sure. Does it really have performance issue?

IIRC, It is not expensive and WebKit/Gtk+ and firefox doesn't keep cairo surface.
