Question

Is there any sort of workaround for the bug that makes firefox flicker when decreasing the size of the document?

Click here for a demo

Click here for the demo in quirks mode (no DOCTYPE)

I bet it could be fixed using javascript — whenever the scrollbar shrinks, make sure to scroll the window up to prevent the flicker or something.. thoughts?

Update: the bug does not appear to be present (or at least not as severe) in quirks mode

Answer 1

Do this:
The problem is that the page scrolls as the image gets resized.

Solution one:
Include the jQuery library and jQuery Scroll plugin.
Then scroll to the image by doing the following:

$.scrollTo("#image", "fast", function(){
  //resize image here
});

OR!

simply disable overflow for the container of the image/page temporarily:

$(body).css("overflow", "hidden");
//do resize
//on resize end (after it has finished):
$(body).css("overflow", "auto");

should solve your problem!

Yes!

//before resizing
var scrollInterval = setInterval(function(){
  $.scrollTo("#image", "fast");
}, 1);
//do your resizing
//once resizing done
clearInterval(scrollInterval);
