Pixellated render issue: How do I revert back to original renders?

EightiesIsEnough

Today, when I tried to render an image, it appeared to be pixellating during the render process.  I prefer the renders which start at the top left corner then render across before going to the next row below - how do I revert back to that format?

In Render Settings turn Progressive Rendering off.

3Delight, I presume? Render Settings -> Progressive -> Progressive Rendering OFF (although Progressive does give better renders). Then maybe change Render Settings -> Bucket Order to the mode you like. I personally prefer the Spiral mode, you get to the interesting bits first.
