This is only using the X11 backend, so it seems a Qt graphicsssystem X11 backend issue. Outcommenting 155 if (!image->hasAlpha() && painter->compositionMode() == QPainter::CompositionMode_SourceOver) 156 painter->setCompositionMode(QPainter::CompositionMode_Source); in ImageQt.cpp / BitmapImage::draw Will make it work for X11, but that way we loose the optimization of using Source (write) instead of SourceOver (read + write)

I think fixing it in Qt can not be that bad. It clearly must happen in a case where the X11 engine passes things on to raster and then back. The question is more who is introducing the black rect.
