It seems I have a similar problem, at least on an overview, launching Civilization IV BTS, steam version. I managed to make a detailed debug.
You shouldn't be posting your problem here unless you've run a regression test for both applications and found they are affected by the same commit. Otherwise file a new bug report because your application is different.
