Strange rendering issue in design workspace

[ccyokes]

I have a model file that has two boards with 3D woodgrain that renders very weirdly. Same lid base is used on a number of other models without issue, and the material is used widely without issue. I am able to open the same file on a different designer's computer and see the same thing and have exported the model and re-imported it and can still see it. Please check the included file and see if you can also see it and tell what happened to cause this. The model was last saved on 2/17/26 with no visual issues until today when I opened it to check a dimension.

It looks fine in the render tab, just in the design workspace it has wild black and white transparency.

The woodgrain looks like this.

Black plastic.

Glass.

And red (similar for all light solid colors)

I see this on two computers. An AMD Ryzen 5950X machine with Nvidia RTX 3070ti and a 2017 MacBook Pro with Radeon Graphics. It looks different on each machine, but it is clearly visible. @Phil.E can you check this out?

The Windows machine is on the most current Fusion release, the MacOS (Ventura 13.7.8) version is 2606.1.36

Has anyone on the Fusion team taken a closer look at this yet?

No solution. As far as I'm aware, no one else has looked into this. The file still shows this issue on my end too, even after the latest Fusion update.

There is something strange about body1 in the LID>FRONT/BACK component. The only workaround is to delete the extrude and make another extrude in its place. Please let us know if it happens again.
