wamp - Three.js: Firefox: Incorrect viewport size: multiple views -

the multiple view not quite drawn total size; 10% smaller window, white space @ top , right. (see image below).

the problem applies three.js example. can tell, it's combination of:

multiple viewports of same scene firefox my wamp setup

to confirm above, i've done following:

if go above link, works fine in both chrome , firefox. point browser re-create of illustration on localhost wampserver setup, displays correctly in chrome, not in firefox. it displays correctly if extract above illustration hard drive , open in firefox or crhome. (bypassing wamp). my project displays correctly if display 1 viewport of scene. (firefox , chrome, loaded via wamp on localhost).

it's (obviously) localhost wamp setup firefox doesn't interferes multiple views configuration (since single-view examples work fine). perhaps headers or that.

is problem code? firefox? three.js? bounty goes best workaround. i'd happy reply questions wamp configuration or else if can.

thanks!
