compiz - May 2008 - Java animations, Google Earth flashing with Compiz enabled

On a Dell Inspiron E1505 / 6400 with the ATI x1400 video card running
the fglrx driver on Kubuntu 8.04, I have some video problems while
running Compiz. I am not using XGL, in fact, I removed it from the
system as it was causing performance issues. The symptoms I describe
here were present before removing XGL, as well as after.

The test applet on java.com flashes (as if it disappears between
animation frames). Google Earth also flashes on manual navigation, but
'sight seeing' animates fine. Google Earth popup dialogs, such as
those for displaying user-submitted photographs, do not display but
parts of their UI do display.

These are my Compiz settings:
$ compiz --version
Checking for Xgl: not present.
Detected PCI ID for VGA: 01:00.0 0300: 1002:7145 (prog-if 00 [VGA controller])
Checking for texture_from_pixmap: not present.
Trying again with indirect rendering:
Checking for texture_from_pixmap: present.
Checking for non power of two support: present.
Checking for Composite extension: present.
Comparing resolution (1680x1050) to maximum 3D texture size (4096): Passed.
Checking for nVidia: not present.
Checking for FBConfig: present.
Checking for Xgl: not present.
compiz 0.7.4

The Xorg direct rendering infrastructure does not support direct
rendering of redirected windows, which means you will get serious
flickering and rendering issues with compiz and fglrx on AIGLX.  The
same is true for the open source intel and radeon drivers.  This will
be resolved in Xorg once DRI2 is stabilized and released, and then the
various drivers will have to be updated.  There is no timetable for
this yet.  This would explain the issues you have with Google Earth,
though not necessarily with java (unless, of course, the java applet is
using your systems opengl libraries).
