To quote the email I received from Wikia support:


 * "Before the Vignette thumbnailer was introduced, rescaling animated GIFs wasn't possible, and although it's possible now, it's still not the ideal use for the tool. Rescaling an animated GIF is generally not a good idea. The tool has to create an entirely new image, and some loss of image quality is inevitable.


 * I'm afraid that we won't develop the thumbnailer further to accommodate this unusual use of the tool, and unfortunately, there isn't a MediaWiki fix I can offer you either. Your best bet is to find images that already have the correct size for what you intend to do with them, or resize them outside of Wikia with image editing software."

It's unfortunate that the team isn't even going to try to fix these graphical glitches. However, you can try to implement Penguin-Pal's solution:

You'd have to ask him about the specific implementation, though.
