Or, maybe your app has wrong linking to *EGL libraries... for example,
your target has own *EGL libraries path,
which is different than *EGL MESA libraries. Check your ldd.

Yes, sorry for that. Three questions:
1. How did you find that 0x300b was EGL_BAD_NATIVE_WINDOW?
a) I searched the source code for the full error message and found that it was
printing the return value of eglGetError()
b) I googled for eglGetError() and found the possible error replies
c) I grepped the EGL headers for an error constant (any of them) and then
found the one close to it that had the value 0x300B.
2. What is this caused by?
According to Khronos docs, a bad EGLDisplay value. Most likely a null pointer.
void QEglFSWindow::resetSurface()
{
EGLDisplay display = screen()->display();
QSurfaceFormat platformFormat = qt_egl_device_integration()-
surfaceFormatFor(window()->requestedFormat());
m_config = QEglFSIntegration::chooseConfig(display, platformFormat);
m_format = q_glFormatFromConfig(display, m_config, platformFormat);
m_window = qt_egl_device_integration()->createNativeWindow(this, screen()-
geometry().size(), m_format);
m_surface = eglCreateWindowSurface(display, m_config, m_window, NULL);
}
Don't ask me why screen()->display() is returning a bad EGLDisplay. This is as
far as I can go studying this codebase.
3. Given that there is no obvious solution, how can I dig further into
debugging this?
