With Kodi Krypton, downloading this image resource pack from the repo results in images that just display as a square of solid color or not visible, depending on platform.
Looking through the git repo, this is the only weather icon image resource that didn’t get bobbled in the commit 6a60e7c “resource images – fix texture packer issues”, maybe that’s the culprit.
Here is a debug log that doesn’t say much about this. On Windows the image is just not visible, on LibreElec on a Pi 3 it’s a solid black box, and LibreElec generic it’s a solid box with color `colordiffuse` of the image. Jarvis displays the repo version happily, and Krypton displays the individual images from source happily.
Could someone from Team Kodi take a look?
