Confirmed! I had accidentally slid my movable command message window off the bottom of the screen and was unable to get it back where I could see it. I resorted to exiting the game completely and reloading a save so that I could again see the sometimes important messages that appear there. And sure enough, depth and tachometers frozen at 12 o'clock. Six minute video highlight link:
