fix: Dark chrome over dark Mica on Windows 11 from the first frame
The window shows before its first frame, and the desktop fills the unpainted
GDI surface white. Under Direct3D 12 frames go through DirectComposition over
that surface, so the transparent toolbar showed white rather than Mica until a
resize reallocated it. The glass frame now erases it to black, which the
extended frame shows as the material.
