Now found an unusual bug with pipes and window size. If you make the tube and wipe her the end that will be output (after the appearance of brick around the tube), on non-original resolution did not appear red, blue, and green lines, especially in full screen mode. At its original size they appear correct please.
That makes it even worse, but I know what you are saying. Edit: There is a piece in the code called "ctype" which allows pipe to move the particles. Fancy display must not be displaying them. This also occurs with the "life" variable in acid.
