Is a different texture set on stage 0 before the texture is actually freed?
Resources are kept alive as long as they're referenced by the device /
stateblock, even though the refcount may fall to 0. A
IDirect3DDevice8Impl_GetTexture() call for example would bump it up to 1 again
in that case.

If I'm reading the disassembly there correctly though, it's trying to call
IDirect3DTexture8_Release() on the texture, which would only make sense if the
application is still supposed to hold a reference to the texture at the point.
