This small topic is for everyone, who have struggled with
SSAA weird effect, which made whole scene white.
First solution is just to revert to older revisions of three-js. I personally used revision 0.138.3 and the issue didn’t appear anymore.
Second approach, which I lately accidentally discovered, was just applying a pass over (after) SSAAPass.
composer.addPass(/* SSAAPass */) composer.addPass(/* BloomPass */)
Hopefully it will save someone hours of coding or tears
P.S. Sorry for my bad english :B
