BlackMagic Design Desktop Video continues to be a pain with FCPX...

I'm at version 10.8.4 of the Desktop Video app by Blackmagic Design, the "driver" app that allows your favorite NLE to output video to an external monitor, and it's still incredibly unstable with FCPX (now at version 10.3.2.) Like I turn A/V Output on in FCPX, and 30sec. later... CRASH!

What game are you guys playing Apple and BMD? I know that Apple allows to output video directly from Thunderbolt, yet I don't have that luxury, I use video cards. Aja does not have that instability.

I am now a year later, two major OS X upgrades, and two major FCPX upgrades from when I first posted this problem, and I'm on a different machine!

Why is it still unstable. Why?

Users have to go back to version 10.4.1 of the app (released June 10 2015!) to have some stability:

FCPX Crashing w/Desktop Video + Ultra studio Mini

Really? Well thank you for making it available, but one would thing that after three full versions releases you would have fixed this pesky Desktop Video problem, why do you not care BMD?
