My Bluetooth mouse will occasionally freeze for a second, then replay my movements delayed by a second. This "delayed playback" behavior lasts several seconds, consistently lagging a second behind, before the displayed position suddenly fast-forwards to my current mouse position.
This can happen a couple times a day - the rest of the time the mouse is perfectly responsive.
I haven't noticed any system activity that correlates with the delays (such as heavy I/O). Also, the mouse has fresh batteries.
I never saw this when using the mouse with the old machine I had - I've only seen it on my new laptop.
How can I go about troubleshooting or preventing this?
