Can you create a video demonstrating the problem when moving windows? If not, please describe which desktop environment / window manager / compositing manager you're using.
Don't think I can show a video as I don't have a high-end camera or capture card, but it affects vanilla Kubuntu 16.10 and 17.04 at least.
