Crop circles appeared on Android emulator and it hanged
The following "crop circles" appeared on my Android emulator AVD
and it hanged. What is this, how to recover from this and disable this?
Probably it is a reaction of keyboard switch and/or shift button press.
Solution
These circles are the multi touch functionality that Android Emulator AVD provides. Are shown when the Ctrl key is pushed. If these circles are activated without holding Ctrl key then you can deactivate them by going to Setting->General->send keyboard shortcuts and change it from Emulator Controls to Virtual Device
