Internet Exploder Strikes Again  
I amused myself over the weekend by, among other things, producing an animated GIF icon from Friday's "I Am Not Good With Boomerangs" xkcd webcomic. (The author specifically OKs this sort of use as long as it's properly credited.)

During lunch, I checked LJ from the office, and found that the bonk-to-the-head stage of the animation had gone all jerky. Suspecting that it might be a browser issue (Firefox 3 at home, IE 6 at the office), I did a few Google searches and discovered that IE's rendering of animated GIFs automatically increases any frame of less than 6/100s of a second -- not to 6/100, but to 10/100s. That's just enough to insure that any frame that was assigned a fast turnover because it's critical for smoothing the animation will create a moment of visible jerkiness.

I'm trying, and failing, to think of a reason for this other than somebody actually going out of his way to be extra inept.

Retweaking the animation is trivial, but will probably have to wait till tomorrow.

I have GIF animation disabled, so it's not an issue for me. What I see is a figure holding something which I recognized as a boomerang because I'd seen the comic recently. Otherwise I'd probably have taken it for a torch blowing in the wind. It's not a problem anyway.

That's another point I need to keep in mind; the first frame of any animations needs to work as a static icon.

Mostly, I'm befuddled by whatever "thought" process could have produced this result. "Frame times less than X get converted to X because X is the fastest we'll guarantee being able to handle" makes sense -- this... not so much.
