Selection would stay (once implemented, way selection is not in there yet)
invariant regardless of painting style/implementation.

Hmm :-)
The current zoom is printed to console, but your zoom was either 448 or 537.
But generally it seems like a problem with graphics drivers or java's drawing
library. The color is one of the highway colors, not any area color, so rendering
of wide lines seems to be broken in specific cases.
I can't reproduce the problem on my side. Could you try playing with Java2D demo
($JDK/demo/jfc/Java2D) or updating java or graphics card drivers?
