About a week ago my Samsung Note II started tracking all touch input with a bubble. It acts sort of like mouse trails, although there is only one bubble. I don't remember turning this feature on, and after looking through all the settings and applications I can't find any way to disable it. The phone is running a CyanogenMod 11 Nightly (Build cm-11-20140222-NIGHTLY-i605.zip) but I noticed it on previous builds of CM 11 as well.
Here are some screenshots of the bubble tracking touch input in various applications:
Does anyone know how to turn this off?
