Probably the latter, and maybe rounding errors. I don't see why it  
should drift if the text is all the same size and the same measure is  
used for line-height and background-size, and for vertical padding and  
margins. Where is the lack of precision coming from otherwise?

The point is that there is a way to create a box with an evenly  
striped background in which the pattern is spaced the same as the  
lines of text. Or there are implementation bugs.
