That appears to be the engine exhaust, and in SH4 that can happen when shelling out to Windows while the game is running. Another anomaly might be a tower of steam following the player sub about. The "cure" is to Save the game (using proper SH3 Save technique), exit the game, re-start it, then load the saved game. After that, don't shell out to Windows while playing the game. If it goes away after you save, exit, return, then that is the problem.
