Description klose 2015-12-07 16:04:55 UTC 
We are using SDL with DirectX11 and the gamma functionality of DirectX. 

When switching to fullscreen mode and changing the gamma everything works fine.

But when pressing alt + tab and then restoring the window, the window does not switch to fullscreen mode properly, the gamma doesn't work anymore.

DirectX outputs the error: DXGI ERROR: IDXGIOutput::GetGammaControlCapabilities: This function can only be called if TakeOwnership has been called. [ MISCELLANEOUS ERROR #47: ]

But calling TakeOwnership doesn't solve the problem. Switching back to window mode and then back to fullscreen solves the problem.
