Public bug reported:
with MIR enabled, unity8 is constantly using at least 100% CPU, even
when the device is idle
TEST CASE
1. Flash a device and enable MIR
2. Reboot and unlock the screen
3. Connect over adb and run 'top'
4. Watch top CPU consumers
ACTUAL RESULT:
unity8 never uses less than 100% CPU even when the device is not in use. When
the device is in use it jumps to more than 150%.
The device also becomes very hot.
