Thanks for the log. Sorry it took so long for me to get to it. Unfortunately, it seems to be somewhat mangled. Perhaps you didn't use append mode (">>") when creating it.
In any case, I've independently been working on a new feature for the Mac driver where it will restore the game's display mode after you Command-Tab away and then switch back. I hope that will fix the issue you're encountering.
If you're able to apply a patch and build Wine from source, please give it a test. If not, hopefully it will be accepted into Wine and you'll be able to test it after the following release.
