The example from
QTBUG-43739 can be used to reproduce this if you change all the TextAreas to be TextEdits. Click on a TextEdit and enter some text to break it.
On Android 5.1.1 the window contents will stretch and look weird. On older versions, I see the window blink whenever I enter a character. If I turn on wrapping for one of the editors, the wrapping will be broken while editing on older versions as well.
