Hub Screen detail degrades with use

    Question

  • I have a C#/XAML  Hub App that displays about 30 previews on the main page. The user can click and see the detail page (full screen). The same PNG image 1920X1080 is used for the master and the detail page (re-sized smaller). Each image is made up of a PNG Image (~200 KB) and a PNG Overlay (for highlights ~20KB). Here is a small example:Good preview

    After using the App for a while the previews "disintegrate" as more and more memory is used ?? (I suspect):

    bad preview

    Cache is set to Required, however I have tried all three options (Enabled, Required, Disabled):

                this.NavigationCacheMode = NavigationCacheMode.Required; 

    The entire App in memory is only about 30 MB. The weird part is that it only happens infrequently and does not seem to have a pattern. Some times it works perfectly every time. 

    Any ideas please?
