Using compiz with transparency behind windows and borders on a dual-screen system; all works fine, but the background that shows through with any transparency done by compiz is wrong.
It appears to be using the whole-width image from the display to generate the transparent image, but applying it to each display separately; so it's squished horizontally by 50%, and doesn't match the foreground.
Cripes this is hard to put into words... if anyone can tell me how to grab a screengrab I can paste it somewhere!
