--- Comment #3 from Luke Benstead kazade@gmail.com 2010-07-08 05:19:19 --- The problem seems to occur around line 380 in the log. That's where the mode change is attempted. Soon after it complains about this:
warn:d3d:IWineGDISwapChainImpl_Destroy (0x135568) Something's still holding the front buffer warn:d3d:IWineGDISwapChainImpl_Destroy (0x135568) Something's still holding the back buffer
Which may be relevant.
