Since I upgraded to High Sierra, the Activity Monitor has been relatively unusable for me. When I launch it, it updates for a while, but after a while (especially after a time of high CPU load), it plainly stops updating. I can interact with the application, but its displayed information doesn't update anymore.
Switching tabs sometimes seems to trigger one or two updates, but I still can't see current information.
Does anyone know why this happens and more importantly how I can solve it.
Note: I compile a lot of C++, run some graphics intensive programs, sometimes with debugger attached, while having a VM standby in Parallels. I don't think this VM causes the issue as I've observed this behaviour without it being active. I did not see this type of behaviour before upgrading to High Sierra.
