When the swap chain is destroyed, we reset the swapchain’s layer (set it to nullptr). However we were not resetting the proxyData which would still point to the window’s (NSView) layer. This starts to become a problem in the cases where the swapchain’s associated QWindow is closed (NSView gets destroyed) and reopened (a new NSView will be created) because when the swap chain is recreated again, since the proxyData already exists and points to the invalid old layer, QRhi::updateSwapChainProxyData is never called. This led to an invalid value being assigned to the swap chain’s layer. To fix the issue, make sure to reset the swapchain’s proxy data when destroy() is called.
