See attached file, it opens correctly in Preview app on Mac, but when opened in Affinity photo the centre of the wheel is not visible.

Software details: Affinity Photo 1.8.2 on MacOS 10.15.3

Hi timpa and Welcome to the Forums,

If you disable the Compound layer, you'll see the whole image.  What is odd, we open it with two layers and PS opens it with one layer.  I'm not entirely sure what a compound layer is and on speaking with QA they've asked if you know how the file was put together?  If you can give me a bit more information about the file, it just helps if i need to get Dev to check over it

Hi @stokerg, poking my nose in here 😀 A compound Path created in Photoshop is just a clipping path created using 2 or more shapes, in this one it looks like 2 circular paths combined.

The file has a (vector) compound nested as a mask. Click the small arrow near the parent layer thumbnail to expand the layer then disable/hide the path layer to see the whole wheel. To edit the compound and access the original paths used to create it drag the path layer to above the background layer in the Layers panel then expand that layer - you will see the two paths (circles) used to create the compound. Unfortunately Affinity doesn't display the compound's original objects when it is nested as a mask.
