No. This is how Canvas works in JavaFX. It is a separate node.

link: No, it's because you load the layout two times. Remove the declarations of the panes and it will still work.
link: As PaulMeuris mentiones, the problem is that in B4J a Canvas is a View on its own. I have modified your Test routine like below to log the xView type.

SetScaleX (scaleX As Double) Scales the x axis of the entire Canvas. SetScaleY (scaleY As Double) Scales the y axis of the entire Canvas. SetStroke (Color As Paint) As String Sets the stroke (line) color SetTransform (mxx As Double, myx As Double, mxy As Double, myy As Double, mxt As Double, myt As

Why not put the two views inside a panel and take a snapshot of the panel? Remember that in B4J the canvas is actually a view by itself. I'm not sure whether it is related or not to the problem you encounter.

That is how a HTML5 canvas works. When you resize it, it clears and you have to redraw. If the last parameter in the initialize = true, then it 'resizes' (responsive). It does however 'scale' (does not make it a bigger or smaller canvas with more drawing estate).

Use javafx canvas to draw text with outline. Better to use CanvasExt lib from @klaus but the working principle is the same. To make fancy text you can also use Graphiclib by @stevel05. Some libs released several years ago are gems.
