Why does the preview when you slice a model look like this now where the models don’t look solid anymore?

### Printer
Bambu H2D serial 0948AD560502510
### Printer Firmware Version
01.02.02.00
### How to reproduce
1. Insert any model into the Prepare tab. You can even right click and add a primitive shape or model there.
2. Slice Plate
3. Go to preview tab and you can see the sliced model
### Actual results
<img width="1914" height="996" alt="Image" src="https://github.com/user-attachments/assets/73532529-e11f-43bf-a2b9-265346cd1952" />

### Expected results
Expected to have the extrusion lines be filled in. Orcaslicer on the same PC shows it correctly.
Reinstalling Bambu Studio does not do anything.
### Project file & Debug log uploads
This is the saved 3mf file of the resultant sliced model.

You might try the workaround mentioned in the this issue.
A solution I’ve found is to go into the Preferences, go to the 3D Settings, then remove the checkbox from the “Enable advanced gcode viewer”. This will force the legacy gcode viewer and that works for me. It seems like the new gcode viewer is buggy on some hardware.
You may need a restart after doing this.

I am using version 2.5.0.66
Did this occur on the previous version you were using? You can download previous versions here.
What OS version are you using?
I am using windows 10.
I have updated my drivers to the latest version that I can
OK, that narrows down the possibilities.

Does it look like a solid object when you change the Color Scheme from line Type to Filament?
the workaround didn’t work
I had this issue on previous versions as well
This doesn’t make a difference
Can you provide the .3mf file that you took the screen shot of in the original post?
It is like this when I try to slice anything
It was some gridfinity bins
