Follow-up Comment #1, bug #49017 (project octave):

Offhand, it looks like the difference between RGB and RGBA with alhpa channel.
 The grid is black with an opacity of 0.15.  0.15*255 = 38, which is 0x26,
which is what I see in the color specification.

As a test, try

hold on
view (3)

This should have the grid turned off and it may work.  If it does, then it is
clearly in the grid drawing routine.
