This might be a bug in screenruler. If I change the DPI of the screen and the document is set to 100% (representing physical size), then, the document should change its size. That is, if the document is A4 and I put an actual A4 sheet on top of the screen, changing the DPI should not change the document size.
Nevertheless, the 100% zoom of evince 3.8 is slightly wider in my screen in 3.8 (not smaller)
