WUFI Passive Geometry Display Distorted

[PrecipitateArch]

I have been running WUFI Passive on a native Windows 10 desktop computer without issue for a couple of years.
A couple of weeks ago any file I opened that was previously fine displays with some of the vertical and horizontal lines shifted up in the Z-axis. Please see attached image. It seems to be a graphics/display issue, as the file still calculates the same results and when others open the file on their computer it displays correctly on their screen.
The only changes I have made to my computer around this time are adding a second monitor, and probably some Windows updates. These are things I have tried to resolve the issue and which have not worked:
1. Uninstall and reinstall WUFI
2. Ensure the graphics card specific driver is current and running
3. Revert to my single monitor set-up
I checked with staff at PHIUS in Chicago and they don't have a solution, but have seen the issue appear for Mac users running Parallels. This further reinforces my thought that it's a graphics card/display issue, but I've reached the limit of my technical know-how!
Does anyone have any advice or solutions? I have emailed WUFI support but not received a response yet.
Thank you!
