--- Comment #27 from Bruno Jesus 00cpxxx@gmail.com --- The issue is still present in wine-git, it's simple to reproduce. Just start the Falkirk battle scenario (last from the first campaign), then hold the down key for a few seconds, release it and alt-tab. When you go back to the game the screen will keep moving down forever.
Now alt-tabbing restores the original screen resolution which is awesome.
