Mint-X-Yellow finds custom icon, but Mint-Y doesn't ?

[ThomasAn]

I noticed that several themes do not have an icon for the "application/x-mswinurl" mime type. That mime type itself was not registered by default on Mint 21.3 so I had to do it manually in "/etc/mime.types"

Also this xml was placed in "~/.local/share/mime/packages" and "update-mime-database ~/.local/share/mime" was run.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="application/x-mswinurl">
    <comment>Internet Shortcut</comment>
    <glob pattern="*.url"/>
  </mime-type>
</mime-info>

The png file was placed here for each of the folder sizes "~/.local/share/icons/hicolor/256x256/apps/application-x-mswinurl.png"

Here it gets interesting:
Mint-X-Yellow is able to see the "application-x-mswinurl.png" in "~/.local/share/icons/hicolor/48x48/apps/application-x-mswinurl.png" but the Mint-Y theme cannot.

There is something esoteric and weird happening in how these themes default to hicolor or not and what folders they search.

Any ideas ?
