Not sure if this is a known issue or just some weirdness with my settings, but I occasionally run into some oddities with the site when browsing it from my iPhone.  Certain headings and buttons seem to rapidly switch between two or three different font sizes (usually the white headings, like forum or blog post titles, and buttons like 'Reply').  While the font switches sizes, other content below it jumps slightly up and down; when it's switching between three different sizes, it gives the page a sort of pulsating effect that would actually look pretty cool set to some techno music.  The glitching seems to go away usually within ten seconds or so if I don't touch anything.
