Flight HUD mouse indicator vanishing

The circle thing in the flight HUD that shows which direction a ship is pointing and trying to turn towards keeps vanishing and I have to get out of the cockpit and get back into it to fix it temporarily. With that mouse indicator thing vanishing, I have no idea which direction I'm trying to turn my ship.

There's 2 scenarios that I know will instantly trigger this disappearance:

1) Overload ship power requirements. I have a small hydrogen ship with 4 H2/O2 generators that are usually disabled until I quickly have to refill the hydrogen tank. The moment I turn those 4 generators on and the battery goes over 100% usage, the circly indicator vanishes. Even turning the generators back off to return power use to a low level (4% to be exact), the indicator remains vanished.

2) Using a tiny ship to transport a giant unknown signal ship. Locked onto it using a landing gear, having to keep the circle pointer away from where I want to go to account for violent directional shifts when tapping the thrusters for a split second while keeping dampeners disabled. If I move the cursor too far away from the center, so requesting a violent turn, the circly indicator vanishes as if my tiny ship is screaming for mercy and just gives up entirely.

Both instances are in space.
