That is what Discover looks like on Manjaro Cinnamon. You can’t read anything on the right.
We need a method of changing this theme or we need the package maintainer to realize they must use a color scheme that looks good on an old fashioned VGA monitor. What looks good on your 4K monitor won’t work for 90% of users. That’s why successful package have high contrast basic colors like black on white and white on dark blue. Even black on gray works well for much of the color blind world.
What we have now for Discover does not work for standard monitors.
Well, I’m not knowingly using any Qt theme. Discover “auto-installed” when something else installed. Appears to be the only way to update flatpak stuff.
I will nuke discover.
People gotta stop using Qt for things that matter.
I don’t think Discover is a hard dependency for something that is not directly Discover related. It maybe an optional dependency for something, but you choose which of those you install.
So you must have installed/updated something related to Discover in the first place. Maybe an AUR package?
