A simple page is as follows:
<! Doctype html>
<Html>
<Body style = "background-image: url(1.gif)">
<Div style = "width: 80000px; height: 80000px;"> </div>
</Body>
</Html>
<! Doctype html>
<Html>
<Body style = "background-image: url(1.gif)">
<Div style = "width: 80000px; height: 80000px;"> </div>
</Body>
</Html>
A huge page that defines the background image. In Firefox, drag the horizontal scroll bar to the very right, or drag the vertical scroll bar to the very bottom, and you will find that the background image is missing or the background image is incomplete.
I'm not sure about how big it is. On my machine, over X will certainly reproduce this bug.
This BUG has been found in all Firefox versions so far. Other Browser IE, Safari, Chrome, and Opera do not have this problem.
If an error occurs, you can switch the window or drag the scroll bar.
If our web app inevitably needs to use huge pages under Firefox, it can only be simulated by itself. It uses a floating layer to display the background and dynamically adjust the coordinates of the floating layer.
