Thanks for reporting this. I see the same behavior on my Mac, but if I resize the window, somehow that makes it start rendering the image properly. Which seems a bit like a Finder bug?

Moving this to Theme because that's where the last bug I saw that involved these backgrounds ended up.

Moving again on advice from :spohl.

I checked that I could still reproduce this, and I could once, but not again after a reboot.
