Description
On certain Mac machines (apparently ones without a dedicated GPU, although this theory would need more testing), our app, using QtQuickWidget, crashes on launch.
Looking at the backtrace, here's where the issue is located:

rdi being 0, it may be that the framebuffer isn't created [correctly] ?
