Matte, i have exactly those symptoms you described. Lines in my lower peripheral vision are partly distorted but not interrupted, as far as i can tell.
I went to a few eye docs, but no one found anything. I have a big fat floater as well, which is mainly sitting in the center of my vision... though i got used to that.
The distortion bothers me much more... your post calmed me down a bit though. Hows it going for you lately, anything changed?
