    Description

      When desktop wallpapers are rendered onto displays smaller than the target resolution, the bitmaps are scaled using a simple nearest-neighbor algorithm, causing artifacts around sharp details (as seen in the screenshot).

      Bilinear filtering (or another technique) should be used when bitmaps are of different resolution to that of the display.
