One of the most annoying things after installing Tahoe for me, that for no good reason an ordinary app would randomly lose its focus. In the midst of my typing. This is unbelievably preposterous and I just can't stop hating Apple for this crap. How the fuck this is acceptable? I just have no words. What makes it even worse that I couldn't even complain about it on their support pages - they just keep removing my comments for being "non-constructive". This is some random bug, and many people have complained about it, how am I suppose to make it "more constructive"? Send them the exact configuration of constellations, the number of monitors I use and their positioning angles, log the keyboard rate and delay, the latency, the level of magnetic interference caused by my Bluetooth devices, etc.?

I wonder whether this could be a touchpad malfunction, causing phantom clicks that move focus. To diagnose, you could temporarily disable it and use an external mouse.

Focus stealing has been an issue in windowed multi-tasking environments from the beginning. It's certainly been an issue in all macOS/OS X versions I've used since I started in 2011.

Interesting. This is exactly the problem I've begun to have on my 14" M2 MB Air. I'm on 15.7.3. The issue started with 15.7.1.

Here I've been thinking it's a hardware problem, like some sort of mechanical intermittent. Maybe not.

I appreciate your frustration, but at the same time what is Apple supposed to do? If it's affecting only a tiny number of users, and you just happen to be an unlucky one, and they don't know how to reproduce it, and you can't help them reproduce it, then what? I think they just have to wait until somebody (such as yourself) is able to figure out with some kind of logging what is happening. E.g. the first question to answer is probably what actually gets the focus, if anything? To produce a bug report that at least suggests which area of code might be responsible.

I had a similar problem at one point, then finally figured out it was when I accidentally hit the fn button which triggered the emoji picker window and moved focus to it (IIRC), but it was off-screen because I'd previously used it on a secondary monitor. Reconnecting the monitor and moving the window back to my primary display fixed it. (Obviously, it's a bug to show a picker window outside of visible coordinates, and I think it got fixed eventually.)

But it also might not be Apple at all, if it's some third-party background utility with a bug. E.g. if that were happening to me, my first thought would be that it might be a Logitech bug or a Karabiner-Elements bug. Uninstalling any non-Apple background processes or utilities seems like a necessary first step.

Obviously by shutting the hell up, you ungrateful serf. The beatings will continue until morale improves.

Seriously, though, if you want this to stop, people like you are going to have to start voting with their wallets.

I finally pulled the plug on macOS a couple years ago for Linux, and I haven't been unhappy about it. However, I did make a point of buying a laptop that was well supported on Linux (a Lenovo X1 Carbon that was in the same price class as an equivalent Mac).
