SquareLine Studio causing HDMI & DP link drops

I'm using an XPS 15 9530 with a WD19S, connected to a pair of Dell SE2417HGX monitors(one HDMI, one DisplayPort)

I've had a lot of HDMI stability problems. Have tried replacing cables and swapping ports, but it seemed random. Strangely, I believe I've narrowed it down to whatever monitor has a copy of SquareLine Studio(SLS) running. If I minimize SLS, the monitor does not flicker or drop the HDMI or DP link. If I have it running, it flickers a frame or two or loses the signal entirely at least a few times per minute.

Has anyone else run into a program causing display link errors on this sort of setup? Any ideas for a workaround?

Though it looks like a simple desktop tool, SLS is implemented in Unity. Is there a way to lock it to one GPU or the other?
