RowList with a lot of content on the top of a video - lower devices

Hi all,
I am trying to implement a screen with a full screen video on the background and a RowList on the top of it.

The Rowlist's contentNode is populated by an api call, so it can have a lot of rows and elements in one row. Each item has a full size (item sized) poster in it.
How can I optimise this for lower-end devices? It is running smooth on Roku 3 but on Roku Streaming Stick (3500X) it is very poor and all the posters are "flickering" so these are reloading all the time. 
I am guessing that I want to display too many Posters at the same time. I guess I need to stop them rendering once it is not visible.

On the RowList I have set numRows="2" and numColumns="2", but did not help.
Same for each Poster's loadWidth, loadHeight, enableRenderTracking, renderTracking. No success so far.

Do you have any suggestions how to optimise the structure for old devices?

Thanks,
Mate
