bluetooth mouse disconnects

I’m using Debian Jessie (testing). I have a bluetooth mouse (Microsoft Sculpt Comfort) and I can pair it and use it ok, but after some time of inactivity (around 10 minutes) it stops working, I have to manually touch the set discoverable button on the mouse and re-pair it on the command line.

Bluetooth Mouse Lag

looking for help diagnosing bluetooth mouse lag. I’m using a Logitech MX Anywhere 2, I’ve had it a few years now and it’s worked well on a number of Linux distros. I recently installed Debian 10 and set it up to use Sid repos. In this environment, the mouse does not work as responsively as normal. I’m on a laptop, and the touchpad works perfectly smoothly, and a wired mouse is also perfectly smooth. What I get with the bluetooth mouse is as if the sampling rate is maybe once every 3 or 4 frames.
