DwmExtendFrameIntoClientArea 和最大化窗口

我正在尝试构建一个漂亮的 GUI，在客户端区域具有一些玻璃效果。

我很成功，并且拥有完全由玻璃制成的漂亮框架，但前提是窗口没有最大化。当我最大化窗口时，它只是黑色:-(

通过一些谷歌搜索和实验，我发现，当我响应 WM_WINDOWPOSCHANGING 使窗口无效时，如下所示：

case WM_WINDOWPOSCHANGING: {
  WINDOWPOS* pWindowPos = (WINDOWPOS*)lParam;
  if (pWindowPos->flags & SWP_FRAMECHANGED) {
    InvalidateRect(hWnd, NULL, TRUE);
  }
}

我也会得到玻璃效果我现在最大化窗口，

这只有在我双击标题栏或窗口右上角的最大化按钮时才有效，但是如果我将窗口移动到屏幕顶部。让它折断最大化窗口（Aero Snap）时，窗口会变成黑色。

有人知道这是如何完成的吗？

（我正在 Windows 7 64 位下开发。）

编辑：

我还应该提到。我想删除标准标题栏，我通过返回 0 来响应 WM_NCCALCSIZE 消息，如果没有这个，一切都会正常工作

在另一个系统上的测试，即基本上相同的是成功的。唯一显着的区别是有另一个显卡，AMD Radeon HD 4300 而不是 AMD Radeon HD 5870。这可能是显卡驱动程序的问题吗？

I am trying to build a nice GUI with some glass effect in the client area.

So I implemented it as described here.

I was successful and have nice frame fully of glass, but only as long the window is not maximized. When I maximize the window it is only black :-(

With some googleing and experimenting I figured out, that when I invalidate the the window in response to a WM_WINDOWPOSCHANGING like this:

case WM_WINDOWPOSCHANGING: {
  WINDOWPOS* pWindowPos = (WINDOWPOS*)lParam;
  if (pWindowPos->flags & SWP_FRAMECHANGED) {
    InvalidateRect(hWnd, NULL, TRUE);
  }
}

I get the glass effect also when I maximize the window.

The odd thing now is that this is only working if I double click on the title bar or this the maximize button on the right top corner of the window. But if I move the window to the top of the screen to let it snap there to maximize the window (Aero Snap) the window turns just black.

Does anyone has a idea how this is done right?

(I am developing under Windows 7 64 bit.)

Edit:

I should also mention that I want to remove the standard title bar, I doing so by returning 0 in response to a WM_NCCALCSIZE message. Without this everything is working fine.

Edit:

A test on another system, which is basically the same was successful. The only notable difference is that there is another graphics card, a AMD Radeon HD 4300 instead of a AMD Radeon HD 5870. Could this be a issue with the driver of the graphics card?
