I believe I have the same bug but I'm not sure.
We have some older Gateway T6524's running 32bit installs of Karmic. We
get flickering screens when launching some apps: Firefox, Google-Earth,
AutoCad, Blueprint software, Topographic software, and so on. Sometimes
the machine flicker on and off for a few seconds and sometimes they just
go totally black and then come back on.
Management is not going to spend money on new machine with this economy
and this may be simply an issue caused by older hardware; However, we
never had any problems with previous versions of Ubuntu and we started
with Gutsy.
Below is a 'lshw listing, I hope this helps someone help us. The CIO
isn't happy right now with Karmic.
