--- Comment #21 from Chow Loong Jin (hyperair@ubuntu.com) ---
I was facing this issue with my Logitech MX Master 3 as well, but applying this
patch[1] seems to make it work, quoted here for posterity:
-------------------8<---------------------
diff --git a/include/net/bluetooth/hci_core.h

------------------->8---------------------
I'm not entirely sure if the issue is in Logitech's implementation of Bluetooth
LL Privacy, or the kernel's, but it doesn't seem to work very well together.
The other workaround of removing the IdentityResolvingKey as documented in the
ArchLinux wiki[2] seems to also work, but not quite as well as the mouse
frequently disconnects and reconnects randomly, especially when scrolling for a
long time.
