Fixture Flicker on Console Exit

Hi all,

We have a (v1 physical) Element board with 2 universes, and all my DMX is on U2, with a few ADJ Pars, several Vivids, and 2 Venue Par64 cans, I also have some wireless DMX fixtures on U2.  It's all single chained with the Vivids at the start of the chain, since they are 5 pin, and a 5 to 3 convertor midline, with the rest wired into the loop and terminated at the end with the wireless transmitter. 

I have no issues when I bootup element and load the console, and a show file.  But as soon as I use the CIA (Central Info Area) to exit the console to the ECU (Config Utility Screen) or Power Down the console, I will get random flickering (multicolor) of the Venue PAR64 fixtures.   With my prior software version of Element (2.1) I could just hard shutdown the console, and the flickering would stop..   Judging form other forums here, I thought it may be timing or because we have RDM enabled, so I tried lowering timing, and disabling RDM, along with an update to 2.3.2 (which, BTW, is pretty awesome..), but alas, my flickering remains, and now a hard shutdown of the console is not solving the flicker issue.

Any ideas? (Short of replacing those fixtures, which is going to be a step here soon, but I would still like to figure out the root cause.)

Thanks!

    I don't know if it will matter in your case but I have some Chauvet led fixtures that do very strange things whenever, especially when they loose dmx. Their tech support told me that on the particular fixture I was describing they don't like two things: being dmx'd on the same line as other different fixtures and having a terminator. So whenever I run those fixtures (I am venue to venue) I have to use an opto-splitter and make sure those fixtures are on their own dmx line AND they DON'T ever get a terminator. That fixed my problem.
    I did notice one thing in your message. You said the rese are wired into the loop and terminated at the end with the wireless transmitter. Loop? You don't have a terminator at the end or a wireless transmitter? Just a couple of observations I didn't follow.
    Really try taking those fixtures out of the line and put them on their own run and see if that makes it go away. I'd be curious.
