compiz crashes when I try to run it in natty

[Observer]

Binary package hint: ibus

When I boot into Natty with Ubuntu Classic desktop, compiz windows decorator is either not loaded or has crashed quietly. No windows decorator is available.

Running "metacity --replace" restores the windows decoration and allows me to use the system.

When I try to run compiz with "compiz --replace &", the whole system get corrupted visually even though the system is still functioning and responding. The extent of functionality cannot be determined as the display is all messed up.

By killing compiz from another tty, the session was restored with the following error:

r300: Implementation error: Render targets are too big in r300_set_framebuffer_state, refusing to bind framebuffer state!

When I switch to a lower display res for both my notebook (1024x768) and lcd monitor (1024x768), compiz runs without error.

Increasing the resolution gradually, I managed to reproduce the display corruption which was automatically resolved when the display res change confirmation dialog time out.

Below is the error output when I increase the resolution to 1440 x 900 (ext LCD monitor) and 1280 x 1024 (notebook):
