This is what is called Tree View in KDE (see System Settings ->
Configure -> General -> Classic Tree View). I already have all
animations OFF in Desktop Effects and it doesn't help. I've managed
somehow to disable this animation couple of years ago and it worked
fine until recent system upgrade. I guess I did some config editing,
but now I totally don't remember... :(
