Here is a case showing the difference with the default wallpaper image and
plain color applying the same change the scale and revert quick test. I removed
all the small 3Mib processes and only left the relevant ones below. Hope that
helps to narrow the issue. Feels like the wallpaper image or plain color gpu
memory is not released.
