--- Comment #18 from wanderer@fastmail.fm --- Created attachment 47692 --> http://bugs.winehq.org/attachment.cgi?id=47692 ddraw trace without the bug
I started a new game, generated a new character, saved immediately without doing anything, then exited the program.
Here's Wine output with WINEDEBUG=+ddraw for a run which loads that save file, displays the Help dialog with F1 (exhibiting a text window without the bug), closes the dialog, then quits the game through normal channels.
I don't know if ddraw is actually relevant, but it's as good a suggestion for a place to start looking as anyone has made yet, and I imagine a simple "all" log would be sufficiently overkill that no one would bother digging through it.
