I wish did fix the issue. First of all, if you care about speed, ditch the 'slow' param in .show('slow') and .hide('slow'). This triggers a very performance-heavy jQuery animation. With all the frames you're loosing right now, this will not work nice anyway. If you need animation there, maybe you could try something with opacity instead, since (css-based) opacity animation is very cheap.
