While I did not figure out a solution yet, but I found out some additional information and came to the conclusion that nixos must have built something weirdly. Thus I posted on the nixos forum and will likely only update there: https://discourse.nixos.org/t/how-to-turn-off-gnome-hover-click-on-kde-plasma-and-why-did-it-get-activated-in-the-first-place/36643

You compile your markdown and don’t read it raw? /s

I use vscodium for most day to day stuff and vscode for trying out/“sandboxing” specific extensions like github copilot.

Replace “server” by “os”, “computer” or “software project” and you got me as well.
