Attached file testcase
STR:

1. Ensure you're using basic layers. layers.acceleration.disabled=true, and restart the browser.
2. Load the testcase
3. Switch tabs, go back to the testcase tab

Expected results:

The two canvases should still appear identical.

Actual results:

The second canvas now looks darker.
btw, I hit SourceSurfaceCGBitmapContext crash bug 923290 every time I open this test case in a background tab when layers.acceleration.disabled=true.
