Screenshot illustrating the problem
Version: unspecified (using KDE 4.5.0)
Even when using the Mercator projection for OpenStreetMap (which should not result in any geometric transformation of tiles), Marble displays a blurred map as if the tiles were geometrically transformed or resampled due to zoom level mismatches. An attached screenshot demonstrates the web-based Mapnik rendering side-by-side with Marble's rendering at a comparable zoom level.
Steps to Reproduce:
Select Openstreetmap display with Mercator projection in Marble, compare the rendering to a similar zoom/area rendered by Mapnik at openstreetmap.org
Marble's rendering is consistently more blurred than the original Mapnik tiles.
Marble should try its best to display raster tiles pixel-exactly where possible (maybe by snapping to the optimal zoom levels).

Yes, I totally agree. We're still looking for volunteers to improve the situation :-)
