On some places and at some zoom levels I can see weak horizontal and vertical (maybe) grid lines. Also, on some places these lines are oblique. Mostly over green areas (assume forests) like here: http://www.openstreetmap.org/#map=8/46.851/-83.790 Are these lines real or my W8 display system is wrong? Can others see these lines too?

They are real and seem to be caused by the renderer / stylesheet using a slightly different color for area outlines. Looks ugly.

See this node for example. It is part of four landuses and its position is exactly at the intersection of a horizontal and a vertical grid line.

There is already a bug report for this issue.

That is a sub-optimally done import. See way example. The landuses are mapped as those rectangles. However, I it is a bit strange that the renderer draws a thin line in some zoom levels. It should not because the neighbouring lines are exactly on the same position, if I see correctly.

Yes, the import could have been improved. But the renderer should be able to handle adjacent landuses of the same type without creating ugly artifacts.
