# Direct3D window tweaks

Fix Windows Frame in D3D | FIXD3DFRAME | Tries to prevent D3D from rendering on the whole window surface including the window border. It activates a small trick that cause the program to render to a child modal surface within the main window borders.
Don't move D3D rendering window | NOWINDOWMOVE | Do not try to update the window position and size on D3D rendering. In some cases, the window may be movable but the rendering area does not move with it. In this case, avoid moving the window at all. It is an experimental feature and doesn't always work.
