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.

it might not be related to this bug specifically, bug <select> when 'size' attr is > 1 also draws back bg
