Multiview 16 2.0.2 update incompatible with P2715Q

I updated to software 2.0.2 today and it totally broke output to my Dell P2715Q, so I rolled back to 2.0.1 and it's fine now. I forgot to take a picture of the output, but I either get a green square on a black background, or very large dark grey scan lines over black. I assume that it has something to do with the compatibility with my monitor's native 3840x2160 resolution or refresh rate. It's operates fine at 2160p29.97 and 2160p25 in 2.0.1, but doesn't work at all on 2.0.2 . I power cycled the unit, power cycled the monitor, tried different cables, nothing seemed to get normal output back.

Have since tried 2.1 and 2.1.1, they also totally break my Multiview 16.

Symptoms are on
2.0.2: garbled output over HDMI or SDI.
2.1: no output
2.1.1: crashes randomly, garbled output and small built in monitor turns all yellow.

I'm don't think it has anything to do with the monitor it's connected to, I think the hardware in my MV16 is incompatible with any software after 2.0.1.
