I want to reduce my compiz effects because of my limited graphics card. Is it safe to disable "copy to pixmap" feature on my compiz?

(I'm using 14.04 Trusty Tahr Daily Build)

Yes, it is safe. However, nobody knows what is the setting for. It is reported that it can improve smoothiness in window movement. Try with this option and without. It shouldn't crash.

It is probably an opengl feature – its a way for drawing stuff without getting visual artifacts on the screen. There are better ways to speed compiz and unity up like disabling the animation.

When you turn it off and on you can see that Unity reloads icons which is not surprising – the window manager probably need to refresh everything when you toggled that option.
