Problem with NGUI component rendering?

I have a curious problem with rendering the actual content in NGUI widgets when the underlying panel is moved. For some reason, the content itself doesn't update to correct position even if the bounds are. First image is how it should be and second is how it is sometimes after moving the underlying panel from right to left.

I have tried updating, refreshing anchors etc. but none seem to be working. Any ideas? It seems to be a rendering problem. We are using Unity 4.6.
