Comment (by Purduecoz):

 I've done some more troubleshooting, and this problem only gets stranger.
 I am unable to reproduce the issue on my iMac, which is running an M1
 chip.  I can reproduce this problem almost every time on my MacBook Pro,
 which is running an M1 Pro chip.  Potential issue with number of graphics
 cores?

 I have found a way to mitigate the problem though.  If I choose "Watch
 Demo" from the main menu, the first time Jones starts playing, his image
 is not drawn, just as with the 'human' player images.  If I immediately
 click again to end the demo, and then choose "Watch Demo" again, Jones's
 image is drawn, as are the other character models.  The models then are
 drawn properly until the next time I exit and run the game.  Both the iMac
 and iMac Pro are running ScummVM 2.5.1 (Apple Silicon binary) and MacOS
 12.4 (Monterey) on fresh installations.

 Not sure how best to help someone narrow this down, but glad to do
 whatever I can.  Thanks.
