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!

I have been using WUFI Passive for about 5 months with no problems .. but, I just got a new computer (Windows 11) and I am now faced with what looks like the same issue. Have you learned any more or have you solved this problem? Any guidance you can provide would be very much appreciated. Thank-you in advance!

Hello! Not sure if anyone is still having this problem, but Phius staff might have found a fix.

One of our certification staff had this issue on a computer using a dedicated NVIDIA GPU, and we believe we've narrowed the issue down to the computer's graphics settings, specifically the OpenGL settings.

The computer's graphics settings were left as the system default, and Windows was possibly using both the integrated Intel CPU graphics and dedicated NVIDIA GPU graphics as it saw fit. We think that the integrated CPU graphics and dedicated GPU graphics settings or processes were in conflict, and that caused these unwanted visual artifacts to appear. The solution appears to be forcing Windows to pick the dedicated GPU for all graphics rendering tasks in WUFI. This issue has not resurfaced since we did the following:

If using an NVIDIA GPU, open the NVIDIA Control Panel and then do the following:

1. Click the menu option for "Manage 3D settings"

• Under Program Settings, choose WUFI Passive (*add it manually if needed)

2. Use these settings:

• For "Preferred GPU": Select 'High-performance NVIDIA processor' (this forces WUFI to only render using the dedicated GPU)

• For "Antialiasing – Mode": Select 'Application-controlled' (this was already enabled when we checked)

• For "OpenGL rendering GPU": Select 'Your NVIDIA GPU' (or similar option that references your dedicated GPU vs integrated graphics)

3. Restart WUFI.

Some of the terminology may differ if you're using a dedicated AMD GPU, but the same concept applies: manually shift all graphics rendering duties to the dedicated GPU using AMD's control panel, and it may fix the issue.

We hope this helps!
