Yeah I use vertex mode. You gotta realise that these issues are very rare and only happen maybe one in ten times and even when they do happen they only last a split second. The recording I took was an exception where it was really bad for some reason. Most people wouldn't notice these things, so saying nobody else has this problem is assumptuous.
It's not just a flicker, if you notice carefully surfaces actually become removed momentarily. Also my config has not changed through different graphics card revisions.
