--safe-mode fixes the issue

So I guess there QOpenGLWindow is used even though we know, it is not available.

Looks like this is expected because the widget is created unconditionally. What is the Qt6 compatible counterpart to QGLFormat::hasOpenGL()? @m0dB

mixxx/src/mixxxmainwindow.cpp

Lines 231 to 235 in 8a16387

	#ifndef MIXXX_USE_QOPENGL
	// Before creating the first skin we need to create a QGLWidget so that all
	// the QGLWidget's we create can use it as a shared QGLContext.
	if (!CmdlineArgs::Instance().getSafeMode() && QGLFormat::hasOpenGL()) {

this might fix it...

Not sure if that's the correct way. I will prepare a PR with a proposed fix.

I have already one in progress. Testing works. Only need some final look.

Here it is: #11963

QOpenGLContext::isValid() suffers the chicken egg issue. The returned value is currently only significant with a widget. But it crashes before we can check.

In the PR I have revived the QGLFormat::hasOpenGL() for the QT5 case (Mixxx 2.4 is Qt 5) and checked QOpenGLContext::create() of a dummy context in case of Qt 6.

This fixes the issue for 2.4 and the main branch.
