[Qgis-developer] Raster: multiply causes NULLs to be painted in black?

[Paolo Cavallini]

Hi all,
on current master, if I load a coloured TIFF, it is displayed correctly.
If I change the blending mode to Multiply, the NULLs (0s) are displayed
black, and they remain black even if I switch back to Blending=Normal.
On 2.18, the same TIFF is displayed as expected.
Sample image available. Should I open a ticket?
All the best.
