If the bug is solely in blend, then it should not affect the OpenGL output or
any other output rendering subpictures via hardware blending. Conversely, if
it affects all outputs, regardless of rendering, the bug is probably in the
Of course, it could also be that blend and the video outputs suffer from
separate instance of the same bug.

With Laurent AWOL, I'm afraid nobody knows the code paths much.
