P2: Important Description
QQuick3DXrManagerPrivate::createSwapchains() crashes on line 1061 (see stack trace below), apparently trying to access the first element of empty m_depthSwapchains. Depth swapchain XR_KHR_composition_layer_depth is an optional feature and not required for a conformant OpenXR runtime (though most runtimes support it).
Still it seems the Qt code tries to keep compatibility, earlier in the code depth swap chains code blocks are surrounded by
if (m_compositionLayerDepthSupported && m_depthSwapchainFormat > 0) { .. }
condition, but fail to make the respective check near the crash.
