fxruby users - Feb 2008 - FXRuby for 2D drawing

Hi, I''m working in a application for generating 2D charts with FXRuby.
I use a FXPNGImage to off-screen drawing. But, the canvas repaint has
many flickering, I don''t think it''s a problem with my machine
because
I use Java2D with almost no flicker effects.
So: how can I significantly reduce flickering effects when drawing
with FXRuby components?
Thanks.

I think I would try using double-buffered drawing to see if that  
improved things. See this question from the FAQ for some ideas:

Hope this helps,
