I just recently noticed that this was a new bug. However, there seems to have been some change in 3.7.4 behavior of the NGUI panels no longer changing the internal local positions of their children.
NGUI Panel (Soft Clip or Contrain but no clip)
--UIGrid
----Widget
----Widget
----Widget
If I anchor the panel to a widget that is anchored to the camera's bottom left, the UIGrid's position doesn't seem to update when I change the aspect ratio. As a work around I am adding a widget to the UIGrid object and anchoring that to the UIGrid's parent. Was this an intended change? Did anyone else notice this problem?
NGUI Version: 3.7.4
Unity Version: 4.5.4p3
Thanks!
