Yes, it's a known issue, and no it's not deliberate.
The reason it wasn't reported before is that people don't use the Skin selector (for some reason), and thus never 'tried' Wuthering before.
Wuthering happens to have a media query that removes its stylish borders when the browser window gets too narrow, and does it with a minor animation.
All browsers check the media query when refreshing the page, and use the media query states to show the page. Animations are discarded.
However, for some reason (thank you Microsoft as always), IE10 decides that when it loads a new page (e.g. you click a link Inside the forum), it should start with the default state and then execute media queries and their associated animations. Other browsers don't do that.
You know how it's called... It's a browser bug.
I'm hopefuly that they will eventually fix it, though. It's only a 'preview' on Windows 7... I don't know about Windows 8.
An alternative, of course, would be to add a custom rule for IE10 to drop the animation. I don't like the idea, but maybe I should implement it ASAP. IE users aren't really worth my time. I want IE to die, even if IE10 is rather usable.

(Fixed. Also fixed here for your comfort, even though wedge.org is not using the latest revs.)
