Created attachment 36502 [details] Test case Setting CAIRO_EXTEND_REFLECT on a pattern created via cairo_pattern_create_for_surface() results in loss of alpha channel. See the test attached - top left quadrant of the window is painted using CAIRO_EXTEND_REFLECT. One would expect the same background as with other extend modes, but it is black instead. Some experimenting shows that the pattern is blended with black instead of being blended with target surface background, not just loses the alpha channel.
