Decal Pixelation Issue in Adobe Dimensions v4.1.5

I opened a project I created in a previous version of Adobe Dimensions, and the app warned me about new features and format changes in version 4, including a new render engine. After adding new decals (with the same resolution I used before), I noticed the render looked pixelated. I then re-imported higher-resolution decals (around 6000 px wide), but the issue persisted — the render was still pixelated.

I searched online and found that this seems to be a known issue with Adobe Substance (apparently fixed as of Oct 2025), but it’s still happening in Adobe Dimensions v4.1.5. I had no choice but to reinstall version 3.4 (Intel Mac) and redo the project there, where the decals render correctly.

Is anyone else experiencing this decal pixelation issue in Dimensions v4?
And does anyone know if there’s a fix or timeline for resolving it?
