My experience with roku dev is limited but in my own channel
Development which is also complex, Since I employ a lot of special
Effects, complex menus, and grids. I have never seen any drawing
Taking place without specifically telling it to draw.
Your example appears to wrap a compositor around each sprite
This is a mistake. You only need one compositor attached to one
Screen. And create sprites from the one compositor and
Write to the one screen Any other compositor you may wish
To use on the one screen should be attached to a bitmap
This allows you to abstract a complex interface into one
Composite. Such as a sliding menu system
The 2d API is primarily for games. So if you are going to
Develop application interface. You still have to play by
The same rules you would in game development
