Changing the filter to CAIRO_FILTER_BILINEAR should restore the speed. An actual fix will require adding code to pixman so that the filtering can be done in the X server. Otherwise making images into pixmaps in an attempt to speed things up actually make it slower as they just have to be read back into the client program to do the transform. It may also be necessary to implement 2-pass filtering.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
