This looks like an Acrobat rendering issue.

I observe the same here on the Mac. Things are fine in Preview. In Acrobat the display is the same as yours at 200% magnification, but things get right switching to 400%. See the attached screenshot, Acrobat top, Preview bottom.

Increasing the magnification by units of 10, things get right when switching from 210% to 220%.

I don't use Acrobat generally for displaying PDF files, only for manipulating them (extracting pages, combining files, comparing them, adding OCR, etc), so unfortunately I don't have much experience with rendering issues. I tried playing with the settings in Preferences > Page Display > Resolution and Rendering, but didn't notice any effect.
