Hello,

we have a problem with drawing images (using canvas) in Internet Explorer:
We want to show charts (jfreechart). So we create an image for the chart and draw it using a canvas.

In Firefox all was okay. But in Internet Explorer the image was not shown at the first drawing. Form the second drawing all is okay.

I think our problem the reported in Bug 375615 - [GC] Drawing order of image is not correct.

Is there a workaround for this problem?

Best regards,
Philipp Megow

Philipp,

if you are just showing an image, you may use the Label widget. Call its
setImage() method to set the image. This should also be slightly more
efficient as no client-side Canvas/SVG element is needed.
