The colour burst is omnipresent in graphics modes. Even mixed mode with 4 lines of text you get the fringy colour bust issues.Yep. You get it, but it does not mean that the color burst is present. In fact, it is not for these 4 lines. What happens is that the color circuitry in the monitor takes a while to shut down.
I just looked at it on a //e, and the burst stays on for all lines in mixed mode. I suspected that it would, since an intermittent color burst is a definite no-no, with potentially unpredictable results for color monitors. Not only do most monitors take the better part of a frame to recognize that the color burst is on or off, but they do not expect it to change rapidly at all. -michael Parallel computing for 8-bit Apple II's!
