I don't see these blurred pixels on my phone, but note that this kind of rendering can also happen with a vector based map: The application has to convert the vector information to a bitmap anyway, for a given zoom level. When zooming in, it is possible that the app shows a zoomed-in version of this bitmap while it is generating a new one in the background.

By the way, it is not necessary to answer every single comment with a link to your screenshot. It is annoying to see the same thing repeated 5 times when reading the thread.

I answered all the relevant replies individually because I thought that would make those people more likely to see it. Sorry for annoying you.

Same version here though the UI looks very different. I can actually reproduce what you describe but only at low zoom levels, which makes sense: the temporary display of a bitmap at the wrong zoom level is more apparent when the phone needs more time to render a lot of vector data (there is less data to render when zoomed-in).
