Description aronkvh 2025-08-25 22:00:06 UTC

Just a visual issue.
OBSERVED RESULT
When using dark color schemes, the black icon with a tagline for apps from Flathub that Discover uses is practically invisible.

EXPECTED RESULT
The icon should be recolored with the text color and the tagline shouldn't be there at all, because it's too small for anyone to read.

Can you attach a screenshot that shows it happening?

Finally got around to make a screenshot of the black-on-grey Flathub icon

This is a tricky one. The icon comes from the repo itself, and that icon isn't compatible with our symbolic icon re-coloring system.

In the past this icon was colorful, so it worked everywhere, but then FLathub changed it to be a symbolic icon. Presumably it re-colors properly on GNOME.

I see a few potential options:
- See if we can inject our icon recoloring code into the SVG code of the icon itself on Flathub, in such a way that it won't interfere with the GNOME icon re-coloring stuff
- Propose to Flathub that they return to using a colorful icon that doesn't require re-coloring anywhere to avoid this issue
- Decide that we can't assume anything and always put a white background square behind the icon we get from the repo
- Stop showing repo icons
