My sigil is now crashing with the following OpenGL error.
Code:
Error info: Fatal: Failed to create OpenGL context 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)
Sigil version: 0.9.16
Runtime Qt: 5.12.6
Compiled Qt: 5.12.2
Platform: Linux
This happens when I open a valid epub book with Sigil. The Sigil window appears showing the contents of the book, and then it posts a dialog with the fatal error in it. The only option at that point is to close the dialog, and Sigil goes away.
I read online that this is caused by stale graphics drivers, but an update to my system a few minutes ago installed a new version of the Nvidia driver. The update did not fix the problem. As far as I can tell, all of my other graphics programs are running fine, before and after the update. Even Blender runs, and that goes straight into OpenGL.
This is probably a system problem or a QT problem rather than a sigil problem, but any pointers to where I can start looking would be appreciated.
Here is my system info:
