`delete s_d.take(this);`

auto *d = s_d.value(this);
  if (!d) {
      d = new ManagedTextureNodePrivate();
      s_d.insert(this, d);
  }
  return d;

Can you perhaps prevent creation of the `ManagedTextureNodePrivate` for this check? `d_ptr()` would create it just to then see that its `textureTracker` is `null`. (Might be worth profiling, though)
