ScummVM version: git 56cf0ccabb56fcea3e6633e17765d617ac227505
Language of game: English
Version of game: CD Macintosh release (with SCN files)
Platform and Compiler: Linux/amd64, g++ 4.8.2
The subtitles in the Macintosh version seem to be all black for me. It only happens for subtitles though. Object descriptions seem to have the correct color. I'm attaching a few screenshots for comparison.
It works fine in my DOS CD version with GRA files, so I suppose it's Macintosh version specific.
Replicated with the DW1 Mac Demo from here, so no need to own this game variant for a developer to investigate:
