screen flashing when component updates

well having now re-read the doc, I suspect and hope the answer has something to do with me not listening to itemunfocused to hide panels and not using replaceChild to replace existing nodes with new nodes, rather than just updating the existing nodes contents.  Will give that a stab today, cheers all.

All I noticed with the screen flashes is - if you have everything on the screen set up within the same component, anything which changes in that component causes the entire screen to redraw.  If you will only be updating a single item on the screen then split that into it's own discrete component, and then when you update that item it will only redraw that little piece.

As a second thing - the first time a drawn screen is populated the screen flashes.  I think that is by design in the firmware.  But once that first flash happens subsequent changes don't flash the screen.

Thanks destruk!
Following the docs and using the "nextpanel" field I have the flashing greatly reduced, but it's still apparent, when nodes are first added to the panelset.  Wonder if I'm doing it wrong or if there's a trick to it, or this is just an unavoidable side effect of OverHangPanelSetScene, or maybe of every component if it's caused by what you're saying "the first time a drawn screen is populated the screen flashes"

I looked at it for a couple of weeks and couldn't figure out a fix for the initial flash.  So I moved on to other problems on the list. 😞
