Hi, I've upgraded my MBA to Yosemite today, and I've noticed this little annoying bug. I'm wondering if everyone has this, or if it's just me. When running on battery and using a bluetooth mouse, the mouse will stutter occasionally. The easiest way to reproduce this is by leaving the mouse in a spot for 3 full seconds, and then starting movement again (while on batterypower). The movement will not start for about a half a second, and then stutterjump to the current location. Can anyone confirm this bug? Else I'll do a fresh install to see if it's upgrading that caused it.
