I'm two weeks behind since I stopped watching over the holidays, but Google searching the forums didn't show a mention of anyone else noticing this small bug, and I even just pre-ordered and downloaded the code (something I was wanting to do soon anyway) to see if it is fixed in the current version and it isn't yet. In the StretchDIBits call that puts the game on the screen, when you changed it to have a 10-pixel offset from the top left so there's some black there, you forgot to add the offset to the target width and height, so right now you're actually shrinking the screen slightly.
It's obviously not shipping code, but you did say it was kind of nice to do the 1-to-1 pixels during development.
Also, the purchase confirmation email for the pre-order doesn't actually mention Handmade Hero anywhere. Would be nice to have that to make it easier to find later. : )
