Huh. For me there are always trails, and lights have a bit of extra shine to them. I usually get the stained-glass windowpane overlay and a bit of squirming, but I haven't seen anything strong enough to melt stuff in 20 years. The acid I find now is all chill and weak, but it's clean and I'm getting older so it works for me.

I did get some refined psilocybin chocolates at deer creek last year that absolutely melted everything and had virtually none of the negative side effects of shrooms.
