Composer lag

### Steps to reproduce

1. Where are you starting? What can you see?
Over the past week or so I've noticed worse and worse lag when typing in the normal, non-WYSIWYG composer.

I've been signed in forever, have slept/woken the computer a few times since the last reboot. There's no typing lag elsewhere on the machine.

Element is using between 5% and 30% CPU and ~1GB RAM.
Machine specs:
