I am seeing a fairly consistent error using Sigil. This seems to happen the first time when I am opening a non-Sigil standard epub from within a calibre library with a space in the library name using the Open with plugin
Code:
Sigil has encountered a problem.
Sigil may need to close.
Error info: Critical: ARB::createContext: wglCreateContextAttribsARB() failed (GL error code: 0x0) for format: QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples 0, swapBehavior QSurfaceFormat::DefaultSwapBehavior, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile), shared context: 0x30000 (The operation completed successfully.)
