I'm using two ImageButtons in an UpdatePanel to display an image which is redrawn every time the update panel refreshes. Since the drawing takes a noticeable time to complete, the image used to flicker on postback. I have double-buffered the image by loading
the image first to ImageButton2 on postback, to be ready to be loaded directly to ImageButton1 on the next postback.
This has resolved the flickering issue on IE and Firefox, however on Chrome the flickering remains. Why might this be?
I think the issue is similar to that detailed in
