Windows that resize themselves while in windows are spread (Super + W) leave old pixels behind

I can't reproduce that. Which GPU/driver do you use? Which version of Ubuntu? Which version of Unity?

GPU: X calls it "Intel Arrandale" using the i965 DRI driver
Ubuntu: Precise
Unity: 5.4.0

I *think* I'm using Unity 2D, but I'm not sure.

If you run xterm, and enable window ops (available in the menu from
CTRL+right-click), you can run this bash command to reproduce:

for (( I=80 ; I>=20 ; I-=10 )); do echo -e "\e[8;30;${I}t" ; sleep 2 ; done

Just start that going then hit super+w.

you are using Unity and I think I understand the bug you are facing. I have seen that update manager window resizing like crazy so what you faced was during expo.
