D3D: swap chain is not updated after the window has been resized to a zero width or height #990

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
If the window is resized to a zero width or height, the size of the backbuffer 
is no more updated when the window is resized again.
The problem comes from the SurfaceD3D::swapRect() function that doesn't call 
checkForOutOfDateSwapChain() if the surface has a zero width or height.

surfaceD3D::swapRect(): always call checkForOutOfDateSwapChain() even if

width or height is 0.
