Custom file icons not displaying properly

[th0masp]

Preamble: When I searched for solutions to my issue I mainly found references to custom folder icons misbehaving in older OS versions. This right here might be something different.

So, OS is Tahoe, offending icons are stored on an external drive using exFat filesystem.

I keep a bunch of shellscripts (.command filetype) handy on there with custom icons applied to make them out quickly. The icons were applied by pasting an image in the 'Get Info' dialog. Works fine in older OS releases but in Tahoe they are bugged and replaced with the default shellscript icon.

What happens is that in a fresh Finder window some of them show up briefly, others just use the default icon. As soon as any action is performed on that window (including performing selections or changing the display mode) all the custom icons get replaced with the default one. I can 'killall Finder', navigate to the icons and again - displayed as long as they are not being interacted with.

Any idea what might be the issue here? Some overzealous security setting perhaps? Something related to external drives or the fact I'm using exFat? Already tried cleaning out icon caches to no avail.

And does this happen to the same files if you copy them to your Mac drive?

Could have really thought of that myself, couldn't I?

Yeah, works fine on the internal drive. But of course that's not where they should reside from now on...

So - permissions, cache, what am I looking for? System is brand new and almost vanilla so there should be zero cruft messing up things.

I guess something isn't fully compatible between Tahoe and exFat. That's just my speculation. To test this theory you can try another external drive formatted differently and see if the problem persists. I assume you need exFat for cross-platform compatibility anyway though.
