SetRenderTarget, Invalid Call error spam using render buffers in directx

[Josh Enes]

This can be seen using the nightly build and running the Teapot On TV sample under DX9. The error:

:display:gsg:dxgsg9(error): SetRenderTarget at (c:\buildslave\dev_sdk_win32\build\panda3d\panda\src\dxgsg9\wdxGraphicsBuffer9.cxx:488), hr=D3DERR_INVALIDCALL:
Invalid call
c:\buildslave\dev_sdk_win32\build\panda3d\panda\src\dxgsg9\wdxGraphicsBuffer9.cxx 488

I believe this may be due to recent-ish changes in the GraphicsStateGuardian.

The same problem.
And always there is a black card at the left-top corner of my app window, if I use base.win.makeTextureBuffer.
If I have three buffer created with base.win.makeTextureBuffer, the last is showed on the screen.
I do want to konw how to remove it.

Sorry, I should have said:
Code:
prefer-parasite-buffer 1

in your Config.prc file.

I found this topic, and after I added "prefer-parasite-buffer 1" in my prc file, the black card was removed sucessfully.

This issue has been fixed thanks to zhao and 11thpenguin.
