Further potentially useful information about the behavior after PPA install: If you remove a device via the ui, it leaves a ghosted version that may or may not be able to reconnect if the device tries to. You must remove this ghosted device (two removes in total) and then it appears to allow a fresh pair that works perfectly. No actual need to restart bluetooth. I tried raspberry pi os (debian port) and this mouse works perfectly and is very snappy / perfect in bluetooth mode, just like with the USB receiver. No amount of hcitool and other tricks (kernel min interval changes) for mouse speed really resolve the issue (nor did it tend to accept the changes I tried). To me, it feels that the poll speed is too high as it does the thing that a usb mouse will do if the poll speed is too high: rubber banding and cursor dances when it finally catches up. It's usable, but sub-optimal. For now, I'm sticking with USB for usability but am around to try things on the BT side.
