These were exported by inkscape in a very problematic way: 1. For each background tile, an opaque rect the size of the full page is drawn 2. The rect is filled with a pattern 2.1. The pattern is an opaque rect the size of the original colored tile 3. The page sized object is blended with an alpha mask As there several of this objects (backdrops and the triangle shaped markers), the whole page is overdrawn 62 times. Current versions of inkscape/poppler do a significant better job here. The rectangles/triangeles are directly drawn with the specified opacity. This reduces the total instruction count from ~100 billion instructions to ~11 billion.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
