Custom icons for documents – show black border :(

I love the ability to use custom icons in DEVONthink for macOS. Especially great is the fact that those icons sync to Devon to Go.

Unfortunately, when I want to use a custom icon for a file, then there’s a little thin black frame border around the icon – but only when viewed in list view. See screenshots attached. All is fine with groups, just not with files. Strangely, the default icons for text items, for example, all the while not being square, they do not have any square border line around them.

Can this be avoided?

What operating system are you using?

I’m using macOS, El Capitan v 10.11.6.

I’m seeing no issue in Sierra or later but Development will have to weigh in on this.

Thanks for the bug report, the next maintenance release will fix this.
