I have noticed this sporadically in previous releases, although I did
not pay enough attention to reliably describe the circumstances.

The problem appeared to be related to the value of the topBits
constant in OverviewMapDataSource.java and the levels values in the
options style file, all of which I altered when experimenting with map
configurations. Different values seemed to have a different effect on
the overlapping areas.

I hope this information is of some value to you: be aware that this is
from casual observation, and may be potentially misleading.
