OpenStreetMap
I found a nice little feature in JOSM: q makes rectangles with 90 degree angles. They look perfect while still in JOSM. Then it gets rendered and I end up with parallellograms. What's up with that? (and more importantly: what can I do to prevent it?)

Check what projection you are using in JOSM - on Edit -> Preferences, then third icon down. It should be set to Mercator, then you'll get things the same shape as they are on the online maps.
