[Compiz] Which plugin is this?

[blazemore]

This plugin I have for Compiz is really annoying me.
Every time I move my cursor to the top left corner, all my open windows appear on the screen.

It's not Expo, and I can't work out what else it is!
See screenshot.

I believe you're experiencing the "Scale" plugin. Perhaps the easiest way to modify its behavior would be to install simple-ccsm and then have a look at the "Edges" tab. Or use compizconfig-settings-manager (ccsm) and adjust the "Scale" properties.

Thanks, yes, it was Scale.
