I can turn off all the UI trash. What I can't turn off is this stupid bug where it intermittently generates spurious keystrokes. I thought until recently that it was the trackpad on my laptop doing it but it happens with an external mouse and keyboard too. It's just intermittent enough that it's hard to pin down, while being frequent enough to be infuriating. The worst part is that sometimes one of the meta keys will get 'stuck down' and I'll have to press them all until I find the one that's 'stuck'. A couple of times I've even had the right mouse button think it's being held down.
