Failures and botched up video output on multiple monitor setup

[nk521]

I have 2 monitors in extended mode.

1. 2560 x 1440 px
2. 1920 x 1080 px

Context: I'm running the mjpegstream example

If I just use any one of these then its fine but the program just fails when I have both connected and I try to record from the primary (index 0) monitor! This is the failure output -

Registering stream 0
Registering stream 1

But on non-primary monitor I get output like this -
