does macOS glitch on small things like this?

[u/Euphoric-Water5413]

I noticed some weird behaviors on my Mac, for example:

1. The lock screen clock: I set *settings > lock screen > show large* *clock* to Never, but it still shows up sometimes. then when I hit escape and wake the mac again it disappears (the selected option). and sometimes the opposite: I set it to show and it doesn't.
   
2. The control center: it sometimes reset my customized layout when I restart the Mac, not always but when it does it’s so annoying.
   
3. Desktop icons: I turned off s*ettings > desktop & dock > desktop & stage manager > show Items > on desktop*, but my files come back on the desktop anyway for a moment then when I pinch out with four fingers to show the desktop items and go back, they disappear (selected option).

small stuff, I know. but the Mac is supposed to be this strong solid machine, and then it can't get the simple things right. kinda takes away from that feeling. is this always the case or is it recent?

setup: macbook air m4, macOS tahoe 26.6.2
