James,
Found out was a bad pixel/board? I noticed that when a fast command would be sent only first half of pixels would be proper color, if the command was over a second then was no problem, so I cut those two pixels out(not sure if problem was coming out of last good lit, or was it first that was affected by fast command, so cut both) and replaced, Now no more stuck or weird color pixels when under a second command sent. It worked fine otherwise, if did sweeps or color changes. What made me find it was when doing a rgb test on each pixel down the row, I saw sometimes it worked and sometimes it did not. Tricky mick it was to find. Now I have another small problem, but that will be another post....lol
