After being powered on for a day or more, GNOME becomes really slow, something which is solved with the command:

killall -3 gnome-shell

However, as soon as I do this, parts of the screen start to lose focus. It seems that pointing the mouse to those areas restores the focus for a moment, but areas far away from the cursor are intermittently shifting focus. This behavior is gone once I restart the computer.

I suspect there's a process that is killed with the command above and isn't restored.

Is there something that I could do?
