I have the same issue.

I noticed that the minimap's splitdiff option doesn't work if the splitdiff's "override highlight color" option is set to true, and also the minimap splitdiff doesn't change its color if the "override highlith color" option is set to true while the minimap's splitdiff option is already enabled.

I encountered different ways in which the bug appeared: it was always related to the option "override highlight color" and the minimap.

Getting the same error here. Has this bug been here for over 2 years ?
