Custom folder icons are blurry
Custom foler icons that are not perfectly square, remain blurry in the latest Mojave update 10.14.5
This is not as described in the Apple instructions: https://support.apple.com/guide/mac-help/create-custom-icons-files-folders-mac-mchlp2313/mac .
Workarounds to create perfect squares exist but a simple copy/paste of any format worked as described in the Apple instructions before Mojave.
So this is still a bug.
