！htrace -diff デバッグする漏れを処理する、私はCallStackを表示しないような多くのハンドル（おそらく漏れているもの）を手に入れます：
これを理由で、どんなオプションがさらにデバッグする必要がありますか？

更新 ：ハンドルリークはグラフィックドライバやグラフィックカードに依存しているようです。特定のグラフィックカード/ドライバを持つWindows XPシステムでのみリークするWPFの任意の形式を使用すると、リークが発生します。

Calls are performed in kernel mode by ZwOpenProcess routine (http://msdn.microsoft.com/en-us/library/windows/hardware/ff567022(v=vs.85).aspx) and not followed by a ZwClose call. Then the handle leaks. You don't see the callstacks because they are only available when calls are performed from user mode (OpenProcess / CloseHandle).
On an XP SP3, it seems difficult to find the culprit. The solution would be to use the 'Object reference tracing' functionality built in the OS, but this path is paved with issues (see http://www.osronline.com/showthread.cfm?link=198302 for further references). Since you found out this issue arises only when a particular video card is present, you can try to contact the vendor or check for a newer version of the driver.
