Hi,

To test the "copy to texture" fix I did this:

- Installed Precise on a Dell Inspiron Mini 1018 with N10 chipset.
- Installed all updates (dist-upgrade) and ccsm.
- Fired up ccsm, enabled "copy to texture" plugin.
- Rebooted the system
- Re-checked that "copy to texture" is enabled in ccsm
- Plugged in external monitor.
- xrandr --output VGA1 --mode 1680x1050

Instead of two horizontal desktops, they were "overlapped"; on the large
monitor, the top left, 1024x600 area was a "mirror" of what I was seeing
on the laptop's internal screen. Performance is good with no lagginess.

I fired up the "displays" applet and tried to move the screens to be
side-by-side (closer to what a normal user would do). Of course, the
display applet complained about resolutions, so I brought the external
down to 800x600.

With the monitors arranged like this, I tried again using xrandr to set
VGA1 to 1680x1050.

When I did this, both displays got "corrupted" showing garbled, vaguely-
horizontal bands. If I try to type something on the opened terminal
window, it eventually refreshes and shows correctly, but the rest of the
display(s) continues to be garbled. Also, display is extremely laggy,
stuff I type takes about 3 seconds to appear on screen.

If I bring the external screen back down to 800x600 it all works fine
again.

So this is still apparently not working for this use case :( Let me know
if I can do further testing or if some of the steps I followed are
wrong.

Thanks for working on this!
