Comment (by eschnett):
After investigating, the reason for this problem seems to be that the regions do not "wrap around". That is, a fine grid abutting the right boundary does not influence the left boundary of the domain. To remedy this, one would need to teach the weight setup explicitly about periodic boundaries.
Can you switch to cell centred grids? Would this work for you? These should not have this problems.
