      After pulling 5.11 (qtbase, qtdeclarative, qt3d), attempting to open a new scene (File->Open) or reloading now fails on Windows with

      ARB::createContext: wglCreateContextAttribsARB() failed (GL error code: 0x502) for format: QSurfaceFormat(version 4.3, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize 8, greenBufferSize 8, blueBufferSize 8, alphaBufferSize 8, stencilBufferSize 8, samples 0, swapBehavior QSurfaceFormat::SwapBehavior(DoubleBuffer), swapInterval 1, colorSpace QSurfaceFormat::ColorSpace(sRGBColorSpace), profile QSurfaceFormat::OpenGLContextProfile(CoreProfile)), shared context: 0x20002 (The operation completed successfully.)

GDI::createContext: wglShareLists() failed. (The requested resource is in use.)

      May have something to do with the recent bulk changes in qt3d/5.11.

      Same happens with the Studio3D, Q3DSWidget, Q3DSSurfaceViewer that - unlike the viewer - use QRenderAspect with Qt3DRender::QRenderAspect::Synchronous. These already fail with a similar error when initializing for the first time.

      Note that qt3d's scene3d example fails the same way.
