Commented Issue: WP7 page transition error when resuming app [9465]

It looks like using the below combination of transition, caused some glitches to the pages, when u switch to the application, using the Mango multi tasking. Can easily be recreated in the sample that is provided with the toolkit.

(the one below, gives a turnstil effect that is not completed, as shown in 1.png)
<toolkit:TransitionService.NavigationInTransition>
<toolkit:NavigationInTransition>
<toolkit:NavigationInTransition.Backward>
<toolkit:TurnstileTransition Mode="BackwardIn"/>
</toolkit:NavigationInTransition.Backward>
<toolkit:NavigationInTransition.Forward>
<toolkit:SlideTransition Mode="SlideUpFadeIn"/>
</toolkit:NavigationInTransition.Forward>
</toolkit:NavigationInTransition>
</toolkit:TransitionService.NavigationInTransition>
<toolkit:TransitionService.NavigationOutTransition>
<toolkit:NavigationOutTransition>
<toolkit:NavigationOutTransition.Backward>
<toolkit:SlideTransition Mode="SlideDownFadeOut"/>
</toolkit:NavigationOutTransition.Backward>
<toolkit:NavigationOutTransition.Forward>
<toolkit:TurnstileTransition Mode="ForwardOut"/>
</toolkit:NavigationOutTransition.Forward>
</toolkit:NavigationOutTransition>
</toolkit:TransitionService.NavigationOutTransition>


(the one below, gives a slid up effect that is not completed, as shown in 2.png)
<toolkit:TransitionService.NavigationInTransition>

Comments: ** Comment from web user: FourSpotProject **

This bug is caused by the transitions using either projections or render transforms. Regarding your second example, the page slides out using a render transform, but when you get back, the render transform is not removed but instead the projection of the turnstile transition is done.
I've got around this issue by downloading the sourcecode and modifying the transition.cs file by adding e.g.

<code>element.RenderTransform = new TranslateTransform();</code>

to

<code>public static ITransition Turnstile(UIElement element, TurnstileTransitionMode turnstileTransitionMode)</code>

to the second last line of the method.
Hope this helps.
