Description

Expected behavior
When overlaying a raster on top of a vector layer, the Overlay and Soft Light blend modes should blend with the vector as they would with a raster. See fig1, where the Hard Light mode works as expected.

Actual behavior
The Overlay and Soft Light blend modes do not interact with underlying vector layers at all, leaving the appearance of said vectors being overlaid upon the raster. (Figs 2 and 3)

All images are captured with the same layer order, the only difference being the blend mode selected for the hillshade. Note the change in appearance of the contours and road on the bottom of each image between figs 1 and 2.

It appears I am not used to Redmine's formatting. Could someone with the appropriate privileges please correct it for me?

Upon further testing it appears that I am incorrect; blend modes seem to be working as intended. I will reopen if I find that I was originally correct.
