You haven't been cleaning that lower window pane with any window cleaners containing ammonia, have you? Ammonia is commonly used to remove window tinting films in the automotive world. I've always wondered why some car tinting jobs turn to a bubbly mess while others stay perfectly fine for 10+ years. I suspect it has to do with owners not realizing ammonia based window cleaners break down the adhesive.
