Just tested it with 1.10 branch 8e259ad0419b006626d1b283431369d2a8af51e5 (oct 6 ) and this issue still occurs but posts in the forum thread provide work arounds ( issue is caused by ID3D11DeviceContext::ClearRenderTargetView having a different behaviour on D3D11/10 compared to 9: http://msdn.microsoft.com/en-us/library/windows/desktop/ff476388%28v=vs.85%29.aspx )
