Same issue with phantom clicks in US. It started when I updated the mouse and dongle firmware (1.9.85 mouse and 1.7.58 dongle) and persists even when the dongle is not plugged in (running off USB). Software version 3.31.81. The error occurs even in Win 10 mouse settings while testing double-click speed. I have not tried reinstalling iCue or downgrading firmware yet.
Update: I don't seem to be able to roll back the firmware (as others have suggested) but have reinstalled iCue without any luck. Using the mouse on USB without the dongle attached causes phantom clicks as does using it with the dongle but no USB.
Update 2: I have my Corsair mouse, keyboard, and headset plugged into a (powered) USB hub. Moving the mouse USB to a motherboard port (bypassing the hub) seems to fix the issue for now, but this was not occurring before the firmware update.
Update 3: The phantom clicks are back with a vengeance this morning with 30-50% of all clicks registering as double-clicks. Rolled back the firmware to 0.5.64 and it seems okay now.
