Ok, just verfying that you did not have working code for handling the orientation change event and that no longer works.

So you were relying on an unrelated event being delivered as a side effect of the orientation change.
Have you tried using propery orientation change handling in code compiled against 5.2 and verified that this no longer works in 5.3?

You have confirmed that you did not check for the event, but now you claim you did?
I find that pretty contradictory.

If QScreen does not emit the orientation change signal in Qt5.3 then this is a bug and should be reported.
And it would not be a QtWidget specifc bug since it would affect anything that uses QtGui.
