问题描述
我们有一个用户在运行我们的WPF应用程序时看到了Presentationhost.exe的高CPU使用率.用户启动WPF应用程序，CPU立即转到50％，UI挂起.这仅发生在运行XP的一台笔记本电脑上.
我让用户运行adplus -hang，这是使用CPU的线程的调用堆栈.看来问题可能出在wpfgfx_v0300.dll
感谢您寻找...

We have one user that is seeing high CPU usage with presentationhost.exe when running our WPF app. The user starts the WPF app, the CPU goes immediately to 50% and the UI hangs. This is happening on just one laptop running XP.
I got the user to run adplus -hang and this is the call stack of the thread that is using the CPU. it looks like the problem might be in wpfgfx_v0300.dll
Thanks for looking...
