[GB-213] Weaving is not possible, window is occluded DirectX9 fullscreen

[BramTeurlings]

For some reason, the window logic of the SR Platform fails when playing a game in DirectX9 in fullscreen mode.

This happens in:

• Tales of Symphonia
• Trackmania Nations Forever
• VPX (Pinball game)

I think this has to be solved within the SR Platform, either by changing the window logic or making a weaving endpoint that overrides the window logic behavior.

I’ve found the problem and solved it.

Turns out the function in the weaver we use to determine if a window is occluded doesn’t account for windows that are spawned as children of the parent window handle we supply to the weaver.

In directX9, a new window called “D3DProxyWindow” was drawn overtop of the main window which was the same size as the parent. This caused the weaver logic to fail as it incorrectly assumed the window was fully occluded.

The fix is to use GetParent(hWnd) on the child window and check if the resulting hWnd is the same as the one we provided to the weaver before we call parameters->potentialOccluders.push_back(hWnd);

I was able to reproduce this hypothesis with Tales of Symphonia and Trackmania Nations Forever. Both games use this “D3DProxyWindow” window.
