--- Comment #6 from W3ird_N3rd mailme667@yahoo.co.uk 2009-07-04 15:32:34 --- I was able to fix pixelformat 19/64/70 with the patch from Andrew Church in bug #16559.
It looks like when TEXTURECAPS_TRANSPARENCY is enabled everything is about three times this error:
err:ddraw:PixelFormat_DD2WineD3D Unknown Pixelformat! err:ddraw:IDirectDrawImpl_CreateNewSurface Unsupported / Unknown pixelformat err:ddraw:IDirectDrawImpl_CreateSurface IDirectDrawImpl_CreateNewSurface failed with 88760091
I very much suspect that when this unknown pixelformat would be supported the unhandled exception would leave.
But I do not know how to find out what format it requires and how to support that. You can see I've been trying a bit in bug #16559 but have not really been able to get anywhere so far.
This bug is possibly related to bug #5897.
