Right now it seems that the Tulip player does not pre-load its default variable assignments if they contain assets like images or documents.
As a result, when the player is started for the first time, the operator will first see a gray blank image before the proper content is displayed.
It would be great if one could specify that an asset should be pre-loaded into cache before an app is displayed to an operator to prevent this flickering. 
In the example it is barely noticeable but I have seen much worse loading behavior quite frequently.
- Tulip player initial load → no cache
- Retrigger → cached
- App restart → cached
