Here's my personal canary in the coal mine that something must be fundamentally broken in Apple's software development process:
- on a recent macOS version, right click on the desktop, select 'change wallpaper' => the new settings panel opens
- click on 'Custom Color'
- now hold and drag around the 'color cursor' in the color selection circle for a few seconds
- stop dragging and notice how the color cursor continues jumping around erratically (it's impossible to actually select the exact color you want)
- same thing happens when using the linear slider below the color circle
This bug doesn't lurk deep in some obscure part of the settings panel, it's the only way to change the desktop background color. A QA specialist would stumble over this in 5 minutes of trying to break the app.
I made it a hobby to check this bug after each OS update, it's broken since the new settings panel was introduced in Ventura. As a good citizen I also wrote a Feedback Assistent ticket (FB13805690 - 21-May-2024) with attached screen recordings and all, but of course I could just as well have sent that report into a black hole :)
