I suspect at shutdown, the "QScreen" backing the qquickwindow is deleted
before the qquickwindow is closed - when that happens, qt still has gl
resources it wants to release, so tries to acquire a new shared gl
context and release them, before shutting down properly.
But this causes qtmir to try creating a new QPlatformOpenGLContext which
tries to create a Display, while mir is shutting down, and I suspect the
egl state is not suited to that.
Proper solution is to implement a QPlatformOffscreenSurface and use it
on shutdown
