GridView and placeholders that never disappear in Windows 8 and Windows Phone app

I have an Universal App targeting Windows Phone 8.1 and Windows 8.1. Both apps use GridView to display data.

Sometimes, instead of the actual items, just the placeholders are shown. This is known behavior, GridView showing placeholders when scrolling and it does not have enough time to render the actual items and eventually renders them.

But in my case, the placehores just stay there, GridView never renders the actual times. This happens on both Windows Phone and Windiws, so I guess the GridView must be the problem.

Anyone has experienced this? Any clue would be appreciated.

Here is a screenshot, notice the gray rectangles render instead of actual items (like the first one).

enter image description here

The GridDefinition is quite simple:

   <GridView               
            Grid.Column="2"                
            Padding="0,0,0,96"
            VerticalAlignment="Top"
            VerticalContentAlignment="Top"
            ItemTemplate="{StaticResource TrackListingTemplate}"
            ItemsSource="{Binding Tracks}" />

The Item template is just a grid with a TextBlock and some images.

The memory footprint is also ok, about 100 MB.

Not really a great solution, but setting ShowsScrollingPlaceholders=false disables all the placeholders. According to the documentation, empty space should be visible instead of items but this is not the case, the whole GridView frezees for a seconds instead.
