Probably some stupid misconfiguration? But a program that works perfectly
on Win7 and almost perfectly on MacOS, on Ubuntu the window is completely
black and a series of many iterations of the following appear in stderr:
> QOpenGLShaderProgram::uniformLocation(qt_Matrix): shader program is not
> QOpenGLShaderProgram: could not create shader program
> QOpenGLShader: could not create shader
> shader compilation failed: ""
The program uses only standard widgets e.g. QMainWindow, QListView,
QWebEngineView. No explicit refs to QOpenG* anything.
