So they are "against straight lines" still less than half the time, not to mentioned that most of the time the deviation is slight (though perhaps that's what makes it all the more noticeable).
I did miss the one with the stairs on #7.
#3 is interesting. The steel block on the far right, it seems that the top actually does line up with the rest, but what happens is, that steel block cube is more 3D (you can see bits of the top and left sides in addition to the front) than the rest, and so the front face of that cube is out of alignment with the others.
Overall, it does appear that, compared with earlier screenshots, you see a little more of these irregularities in these recent ones. I think the iregularities at #3 and #10 are especially unwarranted, since the blocks themselves are mostly straight, so the imperfections thrown in seem rather random and unartistic.
