I think i found something related to this issue, if i input something on my joystick and move the cockpit camera (using track ir headtracking, so no further inputs after that joystick input) and place the now hidden cursor onto any screen in the cockpit, it will outline the screen with a white border.
Didnt notice this until the recent 1.33.5.0 patch, but it could have been there before it. If i then use my mouse and dont input anything on the joystick, the outline does not appear doing the same thing by placing the hidden cursor onto a screen. Not sure if this is only a fenix thing yet, havent tried in other aircraft but thought id share this here
