gnome shell starts to slow down when opened ~60 windows
Gnome shell starts to slow down when opened ~60 windows.
This is especially noticeable when you click on Activities for overview of all windows.
Also I observed CPU load spike when I do this.
Increasing count of CPU cores, installing most fastest SSD in the world Optane 905P and increasing RAM capasity not helps.
It seems that this task does not scale in any way right now.
