Then it could be the same problem as bug 7128 /
https://bugzilla.redhat.com/show_bug.cgi?id=445331 and friends, due to the
AIGLX code dereferncing a stale DrawablePtr.

However, I thought there was a workaround for this in KDE 4.1.3... but maybe
that only applies when disabling kwin compositing, and the problem can still be
triggered in other circumstances such as the ones described here.
