<title>WebKit Canvas Rendering Bug</title>
</head>
<body>
<div id="intro" style="width: 600px;">
This page uses the rendering engine from <a
href="http://github.com/kanaka/novnc">noVNC</a> to
demonstrate a Canvas rendering bug in <a
href="http://webkit.org/">WebKit</a>. This bug was
introduced between WebKit revision 66240 and 66396.
The noVNC bug is <a
href="http://github.com/kanaka/noVNC/issues#issue/28">here</a>.
<br><br>
When you press <b>Start</b>, the noVNC engine will playback the
beginning of a VNC/RFB session. You should see a complete 1024x768 Ubuntu
desktop rendered below. If you have the bug only the first
few rows of pixels will render. Note that the canvas
operations have succeeded case, but they are simply not
rendering correctly; if you resize the browser slightly,
the entire desktop will immediately render.
