Black flash when changing orientation on iOS device

When I change the orientation from landscape to portrait or the other way around by setting for example
Screen.orientation = ScreenOrientation.Landscape , the screen will very often show 1 frame of black and then change orientation. Surely this cannot be intended behavior but I haven't found anyone on google with a similar issue.

I was able to reproduce it in a completely empty project with different versions of Unity. Bug report already filed, but curious if anyone know of any workarounds...
