Flow Xpress only shows the results about 1/3 to 1/2 way thru the circuit...

Flow Xpress only shows the simulation results about a third to half-way thru the circuit, and then the pipes (or balls) just fade away/disappear. Changing the number of pipes doesn't change this. This was also happening during SW2020. But I want to say it was only happening more recently in SW2020, and it was working normally (showing the pipes all the way thru the circuit) when we first started using SW2020. BUT I don't use Flow Xpress very often, so it might have been in SW2018 that it last worked (we used SW2018 up until around 3rd quarter of 2020). Another coworker is having the same problem, or SW will just crash...

Any thoughts? Graphics issue? Microsoft update? Just typical SW nonsense?
