Steps to reproduce:
1. Open a graph on graphs.mozilla.org (see the URL field for example).
2. Wait for the page to load and the graph to render.
3. Hover over the graph with the mouse cursor.
Expected results: Yellow cross-hairs and a table are overlaid on the graph.
Actual results: Yellow cross-hairs and table appear, but the graph is no longer visible (see attached screenshot).
I can reproduce this bug in official Aurora 7 or Nightly 8 builds on desktop Linux (Ubuntu 11.04). I cannot reproduce the bug in Firefox 5 or Beta 6.
Filing this bug under Canvas, but it might be related to the JavaScript graphing library used on that site instead. I haven't tried to create a reduced testcase yet.

'globalCompositeOperation = "over";' occurs three times in http://graphs.mozilla.org/js/GraphCanvas.js.

Reassigning to Webtools, since it looks like the correct solution is to stop using globalCompositeOperation=over in the graph server code.
Component: Canvas: 2D → Graph Server
Product: Core → Webtools
QA Contact: canvas.2d → graph.server

Looks ok on 2.0 graphs-new.m.o ("Custom Chart" specifically), will fix this for 1.0 since we're not quite ready to switch graphs.m.o over yet.

graphs.mozilla.org is now the new interface (old one is still available at graphs-old.mozilla.org)
Given this and comment 6 do we need to do anything for this?
