This is a different workaround that gives the same results both on Windows and on Wine. It intercepts WM_NCCALCSIZE message to request empty non-client area when a window is fullscreen, which makes the client area cover the whole window, regardless of the decorations.
We could also check whether the application changed the default non-client area dimensions before overriding it. However, as OpenGL or Vulkan aren't able to render over non-client areas anyway, I believe it is fine to override it when Wine D3D is supposed to render fullscreen.
Rémi Bernon (8): dxgi/tests: Add more complete window style checks. wined3d: Override WM_NCCALCSIZE for fullscreen windows. wined3d: Add WINED3D_SWAPCHAIN_NO_STYLE_CHANGES flag. d3d8: Do not modify window styles anymore. d3d9: Do not modify window styles anymore. ddraw: Do not modify window styles anymore. wined3d: Use the same style changes as native DXGI. wined3d: Always restore styles if changes are allowed.
