Apply transition when Resizing AIR Window Stage

Question

I am using FLEX and trying to resize the AIR Application's
Stage - I have a desk app that I want to expand out when I change
state:
The problem I have is that none of the Transitions I have
tried work - it would be nice to gracefully slide down.
Or maybe I'm doing it wrong???
[Code]
<mx:states>
<mx:State name="normal">
<mx:SetProperty target="{this.stage.nativeWindow}"
name="height" value="84"/>
</mx:State>
<mx:State name="expanded">
<mx:SetProperty target="{this.stage.nativeWindow}"
name="height" value="500"/>
</mx:State>
</mx:states>
<mx:transitions>
<mx:Transition id="transition1"
fromState="normal" toState="expanded">
<mx:Parallel targets="{[this.stage.nativeWindow]}">
<mx:WipeDown duration="2000">
</mx:WipeDown>
</mx:Parallel>
</mx:Transition>
</mx:transitions>
[/Code]

This is a bug! I uninstalled AIR 16 and installed AIR 15.0.0.356, and there are no striped lines on window resize. What to do?
EDIT: New information:
Those lines appear and dissappear on mouse move/hover. It looks like lines disappear on "redraw region". Lines are always visible only on right side of window.
EDIT: More info:
I think I found that bug is if you have smoothingQuality="high" like in:
<s:BitmapImage source="{imgCls}" smooth="true" smoothingQuality="high"/>
If I set smoothingQuality to "default", then there are no horizontal lines flickering.
What got wrong with latest AIR so I have this issue?
EDIT: I filed a bug: Bug#3928797 - Display problem when resize a BitmapImage with smoothingQuality="high"
It looks it is related to: Bug#3923037 - Corrupted display of resized images
