[Bug 374748] [NEW] black area on dual screen with compiz

[aze555666]

Public bug reported:

Binary package hint: compiz

Ubuntu release = Ubuntu 9.04 Jaunty Jackalope
Package version = 1:0.8.2-0ubuntu8
What I excpected = having a dual-screen working properly with compiz
What happened = The bottom part of the second screen is black.

I use a Dell laptop (Inspiron 1720) on which resolution is 1440*900, and added a screen on the right which resolution is 1280*1024. Using nvidia drivers 173 (with nvidia 8600MGT), the "separate x screen" option, and compiz as window manager, the second screen has a black band on the bottom (900 pixels from the top are displayed properly, 124 are black).
When I move my mouse to this black area, the cursor is shown,and when I right-click, I can see that this area is working (right click shows the desktop context menu, right click near the bottom shows the panel context menu, but I can see only the first item of this menu since it's the only one not being in the black part).

This problem doesn't happen when using metacity instead of compiz as window manager.
This also doesn't happen on my desktop computer, on which I use nvidia drivers 180 (nvidia 8600GT card), same "separate x screen" and compiz, but the second screen is smaller than the main one (1280*1024 and 1024*768)
