hashcat unresponsive over SSH

[oolonthegreat]

I have a VM instance running on Google Compute Engine. When I SSH into it and then run hashcat, although it seems to be working (it successfully cracks known hashes) it is unresponsive throughout the operation, so I cannot type any of the "[s]tatus [p]ause [b]ypass [c]heckpoint [q]uit" options. I have tried reducing the workload profile to 1, but the problem remains. 

I am not sure if this is actually an SSH related problem, so my apologies in forward if it is.

Here is the CPU I am using for this:
