Bluetooth devices freeze/disconnect - Sonoma related.
Approximately once or twice per hour, my (non-Apple) bluetooth mouse freezes, and all my other bluetooth devices (Magic Keyboard, Magic Touchpad) - will no longer accept user input.
They re-connect after about 5 to 60 seconds (brief on screen pop-up indicates keyboard reconnection).
I'm pretty sure it's triggered by large amounts of mouse activity/input - on a non-Apple bluetooth mouse.
If I use the magic touchpad instead, I don't notice any freezes.
I've had this exact set-up (listed below) for 8 months prior to upgrading to Sonoma - and no issues - but was apparent immediately after updating to Sonoma, so I'm pretty confident it's Sonoma-related.
My guess is it's some kind of buffer overflow with mouse movement data points.
If I notice the freeze quickly, and stop moving the mouse, then it seems to unfreeze more quickly - again suggesting that a buffer clears.
