I apologies, only the pcb program has the option of renderer,
At a glance it would appear its purely down to performance, I've looked through kicad bug listing and while there are complaints about slower performance with the current renderer, its not in the same instance as your video,
I'm running a desktop with a high end CPU and GPU, but i can replicate the behavior when i move 20-30 components in a group,
Essentially the renderer does not clear the old render until it has completed the new one, so while your moving it around quickly it takes a moment to complete redrawing the current instance, and in the meantime you have moved it again, meaning it has to start over. but once you slow down to place it, it displays correctly,
I would put it down to not ideal, but not a direct bug, try a video card driver update.
