Do you have the same issue if you follow the OP’s steps to reproduce it?
• I am seeing the same behaviour but with the Fenix A321. Happens when AFK for 10 to 20 mins. I am able to regain most times by disconnecting my TCA Airbus quadrant and reconnecting (physical disconnection by pulling USB out of the back). It’s like the quadrant times out when not touched. Tried very brief exercise of speedbrakes every few mins and no problems.

• Fenix A320/321 with TCA quadrant and sidestick.

Do you have the same issue if you follow the OP’s steps to reproduce it?
• Yes

Provide extra information to complete the original description of the issue:
• Further troubleshooting and after hearing that @F900pilot was having issues when their controller DISC, I attempted a flight where I had my Logitech G903 Wireless Gaming mouse plugged in and no fault occurred on this flight.

I believe the bug is related to momentary disconnect of or loss of connection to peripherals

I get this exact same problem, at cruise when everything is running fine, I return from being away I either wiggle the mouse or change view (alt+1) and the throttle instantly is at idle. It doesn’t quickly go down, it instantly goes down. It won’t rectify quickly unless I change the view to outside, where it suddenly throttles up. On the FBW A380 the autopilot reengages automatically, however on the inibuilds a330 I have to do that. It’s very annoying and only happens when I return from being away for more than 20 mins or so.
