The fix is easy. Open up the compiz settings manager, and head to the window decoration plugin. In there, make sure the Shadow window box reads:
any -name="katapult"Now katapult will look just fine when next you use it.
any -name="katapult"Now katapult will look just fine when next you use it.
Option "AIGLX" "true".
mv libIndirectGL.so.1 libIndirectGL.so.1.oldas root. I did this, and my compiz works fine, but I may have been solving a problem I didn't actually have when I used it. Since I've finally got compiz working fine, I don't want to tinker. Also, it's possible to simply add
Option "XAANoOffscreenPixmaps" "true"straight to the device section of /etc/X11/xorg.conf rather than selecting it graphically.
