Mapillary is a computer vision company, and they use images to create 3D reconstructions of places. Unfortunately, with that comes the fade effect between images.
Currently, the only way to avoid that is to click on each image individually. They have recently implemented a new design, as discussed in their latest blog post, that the fade effect will be becoming smoother. (Launching the Better, Faster, Upgraded Mapillary Web - The Mapillary Blog)
