That's the notepad window in the compiz alt+tab dialog (everything except the window icon gets scaled).  The key feature is that in the bottom right corner the icon for the window is really messed up (black with a few dots of color).  It's also worth noting that the window icon does not display in the gnome taskbar at all after this patch, just a generic "this program has no icon" icon.  I'm using the nVidia driver version 185.18.36.

I looked into this a little and it appears like it's necessary to use the extended window manager hint _NET_WM_ICON to use 32-bit window icons.  I've whipped up a small patch (attached) that does this and it fixes the problem I'm seeing (both with alt+tab and in the gnome taskbar), does this solution appear acceptable?
