Edit: Looks like you can opt-out of that “new look and feel” pretty easily under the appearance settings but still, whats with putting rounded corners everywhere?
Edit 2: “Explore the web with a softer, more friendly aesthetic featuring rounded corners […] Designed to complement your operating system, whether on Windows 11, MacOS, or Linux.” The fuck does that mean? Windows 11 fair enough but most Linux distros don’t look like that at all.
Closest thing I can think of would be back in the day when colour palettes were small enough that paint had colour blends in its palette, if you filled with one of those, it didn’t treat that filled area as one colour so that you could fill it again with a different colour.
But I wouldn’t even call that a bug so much as a lack of feature. And it was kinda satisfying to fill one of those blended colours and then alternatively fill with the two colours that made the blend and watch it slowly creep out to fill the entire space. Lol I didn’t even realize I still had that memory in the archives.
