Description
Black or transparent browser window was reproduced on AMD Radeon based GPU when using OpenGL 4.0.
Output from application with --log-level=1 (error 0x502 seems to be GL_INVALID_OPERATION):
ARB::createContext: wglCreateContextAttribsARB() failed (GL error code: 0x502) for format: QSurfaceFormat(version 4.0, options QFlags(0x4), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior 0, swapInterval 0, profile 2), shared context: 0x10002 () GDI::createContext: wglShareLists() failed.

This was used to set up OpenGL 4.0:
QCoreApplication::setAttribute(Qt::AA_ShareOpenGLContexts);
QSurfaceFormat format;
format.setVersion(4, 0);
format.setProfile(QSurfaceFormat::CompatibilityProfile);
format.setDepthBufferSize(24);
format.setStencilBufferSize(8);
format.setSwapInterval(0);
format.setOption(QSurfaceFormat::DeprecatedFunctions, true);
QSurfaceFormat::setDefaultFormat(format);
