I have a similar issue. I'm using an Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller rev 3 on an HP NC6220
laptop. The laptop screen is fine, but my SOHO TOPAZ S 24 LCD flickers
once an application or dialog is launched.
It seems to only happen the first time the application
I updated all my intrepid packages to the latest available and that
still did not fix the issue. I ended up turning off the laptop display,
and working only with the LCD and the problem went away. So, maybe this
is related to dual (multiple) screen setups?
