ultrastudio mini monitor crashes resolve 9.1.1

This is what I'm trying to do:
I have a 15 inch retina connected to a mini monitor. Output is 720p.
Now I try to grade using davinci 9.1.1 Lite
After adding a few nodes the program crashes.
Is this a known issue and will there be a fix soon?

I have the latest ultrastudio software installed and i have 16 gigs of Ram

After some testing I have concluded that it has something to do with the displaying of the waveform monitors. Either 2 up or 4 up, it doesn't matter. When they are displayed the program becomes unstable.
Any thoughts on that?
