hi Oli, i cant seem to see any tearing here... can u post a screenshot maybe? nice patch BTW
@l3vidius, i think your issue is separate as oli is using openGL to draw the lissajous curves. your oscilloscope draws directly to CHAR matrix. i think you need to slow down the clear bang so it only does it once it has got all the way across the x dim of the char matrix.
this patch is amazing, have just found it - ive added the 3rd dimension & wanted to share as a big thank you & for further lissajous fun. i prefer green lines & red background for maximum seizure induction x
