Thanks Sean. One of the problems is likely that I'm using Qt3DWindow which calls QSurfaceFormat::setDefaultFormat() in the constructor which I've already called in main(). I'd missed this warning in my application's output because I have a bunch of debug output:
Warning: Warning: Setting a new default format with a different version or profile after the global shared context is created may cause issues with context sharing. (qsurfaceformat.cpp:770, static void QSurfaceFormat::setDefaultFormat(const QSurfaceFormat &)) The docs say that setDefaultFormat() needs to be called before the QGuiApplication is constructed if Qt::AA_ShareOpenGLContexts is set. So it seems like Qt3DWindow shouldn't be setting the default format? Or documented that it's not usable with a shared context? --- Andy Maloney // https://asmaloney.com twitter ~ @asmaloney <https://twitter.com/asmaloney> On Fri, May 5, 2017 at 3:29 AM, Sean Harmer <sean.har...@kdab.com> wrote: > On Thursday 04 May 2017 17:57:32 Thiago Macieira wrote: > > Em quinta-feira, 4 de maio de 2017, às 16:07:12 PDT, Andy escreveu: > > > Fatal: QWebEngine: Default QSurfaceFormat OpenGL profile is not > compatible > > > with the global shared context OpenGL profile.
