The patch does this and it works correctly in DirectX8/9 SDK samples.
I'm pretty sure this can cause a resource leak if it's done on a D3D child window (the existing offscreen surfaces won't be destroyed). Though I can't say I like the idea of the patch since it does nothing for non-Wine, or even non-winex11.drv Wine, to fix the issue.
In the non-Wine case you would need WineD3D child windows. I don't like that and it would be a performance hit. Right now we don't have a functioning quartz driver. When it comes around the function should be ported over.
