In Windows, show() will call forceChildRefresh. forceChildRefresh will calling SetWindowPos twice in this method will cause a white screen problem. I think this is the reason for the white screen....

i will slove it in bitsdojo_window.cpp if (!createParams->lpcs->lpCreateParams) { return 0; } // if null pointer will return **if (!createParams->lpcs->lpszClass) { return 0; } if (!createParams->lpcs->lpszName) { return 0; }**...

isMemoryValid(createParams->lpcs->lpszClass) use VirtualQuery, check memory valid can solve this question on windows.
