    <thetext>I have created a functional canvas element at widths up to 22,000 pixels, with a 2d object drawn at 20,000 pixels (horizontal position).

But as I try to increase the width of the canvas element beyond that width, the 2d object no longer appears.

Code sample:

&lt;canvas id=&quot;mycanvas&quot; style=&quot;position: absolute;&quot; width=&quot;4000600&quot; height=&quot;600&quot;&gt;your browser does not support the canvas tag&lt;/canvas&gt;


&lt;script type=&quot;text/javascript&quot;&gt;
	var canvas=document.getElementById(&apos;mycanvas&apos;);
	var ctx=canvas.getContext(&apos;2d&apos;);
	ctx.fillStyle=&apos;#FF0000&apos;;
	ctx.fillRect(4000000,100,300,300);

&lt;/script&gt;

Expected to see the 300X300px red square just to the left of the page&apos;s right edge (600 pixels to the left), but nothing appears. 

I&apos;m new to this element, so I may be missing something, but this code works fine if the width of the CANVAS element is reduced, and the fillRect horizontal position is also reduced, both under 30,000 pixels.</thetext>
