UINavigationBar red and green flashing

Him


got a strange behaviour on my test devices.

Basic Master Detail pattern with a UINavigationController.

When transtioning back from the detail viewcontroller, the UINavigationBar of the master viewcontroller flashes briefly red.

Ocasionally he flashes green too, but that happens only after a cold start of the application once. Then its allways red.


I dont have any of those collors set anywhere and I remember dimmly that this flashing has a meaning when devoping.


Any hint what the device is trying to say?

If this is the Simulator, the colors refer to the state of graphics blending. The colors are doucmented here.
