Dock goes to 100% cpu and system deadlocks. any cures?
99% of the time I use almost exactly two apps. Iterm2 and Chrome. (and ssh but...)
Since catalina I have had an issue where if I have multiple desktops, each with copies of iterm or chrome active, then swiping between them will eventually make Dock go to 100% cpu. Eventually the system freezes, I get logged out and I have to restore all my windows. I get around this by having Activity Monitor always running, and as soon as the system feel sluggish, if I see Dock going up through 95% and increasing, I kill it.
I have, at work, had two laptops replaced for doing this and we assumed it was a weird issue with the machines but now with the third machine doing the same, and this being a brand new Apple Silicon Macbook pro, It looks to be a problem in the software, and long standing to as I've been seeing this for over 2 years now.
This is really easy to reproduce.
Open some number of desktops.. having them spread across more than one screen helps.
Fire up chrome and have say 6 or more chrome windows spread across the desktops.
sprinkle in a few Iterm2 windows. Now start swiping back and forth between the different windows in different desktops. Within a few minutes (if the windows are active) doc should go to 100% and swiping will stop. Eventually all activity outside whatever app you are in will stop working and EVENTUALLY your session will be killed
This is obviously a longstanding bug.. how does one raise an actual Bug report with apple?
