I have a Web page where an image element is superposed over a canvas element. The idea is that the canvas element provides a low quality version of an image which is eventually replaced by a final higher quality image. Previously, the image contents was loaded progressively over the canvas, in a smooth way (the part not yet loaded was transparent). Now, I get a dark background (instead of the canvas) for a short time when the image starts loading. Then, the canvas becomes visible again, while being progressively replaced by the image. The bug is especially visible over a slow network. To see this, go to the following page: http://www.pps.jussieu.fr/~vouillon/bug2/ Then, when you click on one of the small images on the page, a larger version of the image is displayed as described above. Some images are small and loaded quickly, so you may have to click on several images before seeing the flickering. Using mozregression, it seems the regression was introduced by the following changeset: changeset: 79230:8b89d7037306 user: Matt Woodrow <email@example.com> date: Wed Oct 26 16:24:58 2011 +1300 summary: Bug 695275 - Fix conversion of ThebesLayers to ImageLayers. r=roc The bug still occurs in Firefox Nightly.

Yeah, this looks wrong. Over here (on Mac) I never even see the canvas previews, just the black, with a nightly. Matt, can you take a look please?

Is this still happening?
Jérôme, is it still an issue on your side with FF32?
No, this is fixed now. Thanks!
