Hi,
 
We use stadnard UpdateLayeredWindow API method to make shadow transparent.
 
you can disable Alpha shadow with such patch:
 
BOOL CXTPShadowManager::IsAlphaShadow()
{
 return FALSE;
}

XTP 12.0.1.
 
The shadow goes completely black here. I guess you perform some XOR operation with the underlying GDI, which is (I guess) black.
 
I'm not sure if I'd call this a bug, but it's indeed a problem. The menu is ugly when our 3D window is shown :(
 
 
(Since this is a hardware-accelerated DirectShow surface, I had to paint the white background myself)
