Steps to reproduce:

1. Create a new project using Universal 3D template
2. Import the attached "arrow.svg" into Project window
3. Select the imported SVG asset
4. In the Inspector, change the "Generated Asset Type" to "Texture2D"
5. Click "Apply"
6. Observe the "Arrow.svg" asset preview in the Project window

Actual results: The asset preview in the Project window is fully black, making the shape completely indistinguishable

Expected results: The preview displays the black arrow shape clearly against a transparent or Editor-standard checkerboard background, matching how it appears in the Inspector preview

Reproducible with versions: 6000.3.12f1, 6000.4.1f1, 6000.5.0b1, 6000.6.0a1

Can’t test with versions: 6000.0.71f1 (SVG import does not work)

Tested on (OS): macOS 26.3 (M1)

Notes:

• This creates a very poor UX as all black SVG icons will appear as identical solid black squares in the Project window, making it impossible to tell them apart at a glance
