Good question. The output from `WindowsFlags` is the same on both machines:

WindowsFlags (Java):
  d3dEnabled: true
  d3dSet: false
  oglEnabled: false
  oglVerbose: false
  gdiBlitEnabled: true
  offscreenSharingEnabled: false

Setting `-Dsun.java2d.d3d=True` produces

Direct3D pipeline enabled on screen 0

in both cases.

Disabling Direct3D with `-Dsun.java2d.d3d=false` changes nothing.
