(In reply to Karl Dubost💡 :karlcow from comment #0) > and all these images are in fact videos, not animated gif The DOM for each of these "tiles" actually has both a static `<img>` and a `<video>`, and for the tiles that look static, it seems that the problem is that the video never appears. For me, the images all have `class=".rg_i"`, and if I add `visibility:hidden` to that class, then the 'frozen'-looking animations all disappear, because they weren't in fact animations -- they were just static images. The videos that are successfully playing are still there, and the empty tiles represent videos that are failing to render anything.
