Running WinUAE with the Direct3D filter.

[whabang]

Hi!
I am running the latest version of WinUAE, and whenever I activate the Direct3D filter, the image gets a red hue.
If I refrain from using filters (but I really do want the image to fill the entire screen :-)), everything looks fine.
I have a bog standard P4 desktop PC with GMA 900 video on the north bridge.

Any suggestions? I could try an older display driver, but the older versions had a bunch of rather nasty bugs, that I don't want to run into again.

I find it problematic to fill the entire screen when running in 1024x768. It can be done just fine in 640x480, but my TFT makes that blurrier than the filters would do.
