[Bug 729979] Re: [nvidia] Windows appear blank white


I have this very annoying bug since I've upgraded to 12.04 from 11.04.

I have a Nvidia GTX 460 m and i'm using Compiz

To sump up what I've found :

1) to reproduce the bug. You have to : 
a) minimize a window
b) use spread view (super + W)  and go back to normal
c) maximize the window previously minimized

2) to workaround the bug
a) an instant fix is to change the size of the blank window, even slightly
b) there's two permanent fixes, both through Compiz Config Setting Manager. 

α) The first one is, in CCSM, to go to "animations", and there to change
"minimize animation"from "zoom"  to "none" (and to make sure that focus
animation is  set to "none" or "N/A").

β) The second one is, in CCSM, to unclick Windows Decoration.

They are only workarounds, as they imply to make do without either
animations when maximizing/minimizing windows or decoration on windows
(which is quite useful...).

I'd like to suggest that it's quite about time to find a proper solution
to a bug that's been around for nearly two years and three releases of
Ubuntu, and that affects potentialy anyone with a Nvidia card (that's a
lot of people) and that impairs a basic functionality of unity.
