I think this is caused by the brush not being exactly on a pixel, or something like that.
A possible workaround is to make the grid 1x1, by going image->configure grid.
Make sure the grid is not turned on, and then using the option view->snap to grid.
This essentially make the brush snap to pixels. It isn't very useful when you need to use a grid, but I suppose guides can be used as a substitute, or even a grid drawn over as pixels with some transparency.
