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.

Yep, that was the culprit. Many thanks for your help!!!
