embedded AWT canvas not always repainted [message #441029]

Hi,

I have a big problem with the bridging between AWT and SWT. I use
SWT_AWT.new_Frame to embed an AWT canvas in my Composite subclass
(actually, the canvas is embedded in the AWT frame returned by
new_Frame). When a repaint event of my class occurs, I draw to the
Graphics of the AWT canvas. This works very well as long as the main
window containing the Composite is not resized. If it IS resized,
sometimes it works too, while sometimes the canvas is just filled with
its background color (although the rendering to it was performed).

Thanks!
