From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The problem I've had with bad themes (e.g. black on black text/icons) seem to stem from apps using system/fallback colours, e.g. not defining it's own list background because it assumes it's always going to be white. But I can't say if it happens more often with Gtk or Qt.. Most recently it happened both with GIMP (Gtk) and FreeCAD (Qt)
Yeah, this is true. And it's not surprising that Lutris looks funky. You could get everything on your desktop looking nice and then you boot up Lutris to see a bunch of problems.
You gotta be prepared to dive into apps that opt for those fallback colors and get into their configs sometimes. I've been into .rasi, .toml, .xml, and many more file extensions. Then I grab a color picker app and reverse search the app's colors inside the config to change them to what I want.
I don't know much about FreeCAD, but I know that the GIMP 3 UI can now be changed around with CSS. Sometimes its just your only option without changing your whole theme. Don't forget to save your dotfiles in a repository or just back them up on external if you dive into your configs. It will save you a ton of double work if you hop distros or the themes get overwritten in an update.
