Can I prevent the architect code editor from redrawing every time I type something?

For example I click my controller, view it's code and click the edit button to the left to open up the text edit mode in sencha architect. Every time I type, pause or hit return it seems to redraw the entire controller code and refresh the screen. This means I have to wait, until this is finished and then the insert point is not even where I was last typing.

Is this a setting, bug, or ?
