Hi Marc, I only see the flickering the first time the images are drawn, the second round no more flickering occurs I'm using FF on Vista: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)

Maybe some setting in Firefox I changed? Or a plugin? I am really puzzled. Can someone else reproduce the flickering?
