crash log (Wine 2.8)

Still present in wine-2.8-25-gbe12c5bc4f and Wine Staging 2.8.

Tested with Might and Magic VII (GOG.com) + Grayface patch v2.0.
It seems the unofficial patches by Grayface result in similar problems in MM 6
and MM 8 too, when trying to switch between  fullscreen and windowed modes.
Might and Magic VI crashes just like MM VII, Might and Magic VIII becomes
unresponsive when I press <F4>.
