I'm honestly glad to see this thread exist; I've been having this problem on and off for like a year straight.
To clarify the actual problem, it's that my cursor will not change to the appropriate shape when hovering/clicking on something, and will instead remain the black pointer arrow. Alternatively, it may briefly flash into the correct shape but then revert back to the default black pointer; this is most obvious when resizing windows.
I have an M1 MacBook Pro, from macOS Monterey to macOS Sonoma. I think it started during Ventura? I use Bartender, LinearMouse, and have a Logitech MX Master 3S (for Mac). I also sometimes use my iPad Air as a second display, as well as occasionally the odd regular external monitor. I've noticed it seems to happen more when I use the Logitech mouse over just the trackpad, and that sometimes I can temporarily fix it if I open/close Logi Options+, but this doesn't always work.
Happy to share more info to corroborate with others and find common trends. I haven't reported this to Apple because I didn't even know what to file it as or where, but if someone has a link/method to send in a bug report I'll happily do so.
