>What I do get, is some bluetooth issues (e.g. affecting the mouse cursor. If you start the bluetooth deadmon it fixes itself for a day or so.
Can you elaborate on this? I think i was hitting this as well. Specifically when I scroll or type, it "halts" for a split second every other second. Originally I thought it was a video card failing or something but after a long time I finally traced it to Bluetooth. Since then I have been using wired connection on my keyboard and mouse.
What do you mean by "If you start the bluetooth deadmon"
In my case it's visible in the mouse (the keyboard is wired, mechanical), and it's like you describe, at certain points there is laginess. After some time, it's like the mouse slows down, and lags more.
I've heard this happens when you have some USB-C hubs attached, which I do. Not sure what the connection is -- but I think my Anker hub does causes this.

Sorry, I meant: "if you restart the bluetooth daemon", e.g. "sudo pkill bluetoothd".
a little unclear if you don't have a hub, or do have an Anker hub, but try moving the Anker hub far away from your Macbook and see if you still have the bluetooth issue. You need a USB cable (depending on what's the hub is you might need a 3.1 Gen2) long enough.
For me it was a hardware proximity issue. Powered external devices interfering with the Mac's bluetooth.
