SVG thumbnail backgrounds:

Hi, me and my team members are using Dopus to manage 1000s of SVGs.
We have a black line image set. We want to set the thumbnail background to grey to easily check there are no white items in the images.

My colleague has managed to set the grey backgrounds and also sees the correct aspect ratio :

But I have the same settings and I just see a border colour (that changes if I change fill colour) and the images all look square:

Any suggestions very welcome.

You probably have different SVG thumbnailers installed on the two machines.

If you look at the same files in File Explorer, do their thumbnails also have a solid white background on your machine?
