The problem you describe points to the AFC setting. With this setting, the camera keeps trying to maintain focus. This can be deactivated in the video settings. It is advisable to set the focus to infinity once when flying off (click somewhere on the horizon) and keep the setting deactivated.

Otherwise, everything is the same.
