I want to add that this problem also causes graphical artefacts on some sites even without manually zooming. See
http://playground.kameleoon.net/engine/image_scaling.html
Under Linux, Firefox 3.6.8 will display a red block next to the gradient because the image is not correctly scaled (look at the attached screenshot).
Under Chrome or with a patched Firefox using EXTEND_PAD, it looks as it should.
Therefore please really consider applying this patch for Firefox 4 final; it causes artefacts with perfectly valid HTML / CSS for Linux Firefox users.
