Screen blacking out on Forticlient Mac (6.0.9.162)

Hi. I've recently started using Forticlient to connect to my work's servers while working form home. Overall its been pretty solid, but every so often the screen will black out for 1-2 seconds. It always returns and continues to work afterwards, but its pretty disruptive. Has anyone else on here had similar issues and found a way around them?

Let me know which logs and system info would be useful to help diagnose this.

Thanks.
