Anyone know what is causing cloud animation upon waking?

[TheBundo]

I have been on DC 3.2.3 for a couple months, and never noticed this before a week or 2 back, so I think it must be something I installed or updated. When my phone wakes, or I wake it to do something, there is a second or 2 where clouds go across the screen. It makes for a delay in doing what I want to do. Does anyone know what is causing this?
