Hi all,
Tried the two latest drivers g02 and g03 and both give the same problem. It comes and goes actually and could not find anything on the net or in these forums so figured I’d post it and cross my fingers.
Running opensuse 12.1 with all the latest updates.
asus g73s with nividia geforce 460M
Current driver is NVIDIA G02 304.88
Kernel Linux 3.1.10-1.19-desktop x86_64
KDE 4.7.2 (4.7.2) “release 5”
Really bright pixels just start popping up on the screen, mostly with firefox. They disappear/reappear as I scroll through pages. There are also weid bright lines that appear all over the screen here and there, like coloured shades. I am attaching a jpeg with some of the problems in the browser window (pink regions), on the top left right under the chameleon head and in a couple of the plasmoids. Any idea someone?
Thanks…

Okay, just occurred to me that the bright pixels problem does not appear in the pic unless it is present on the computer. The displayed pic does not show it anymore because it is not happening on the laptop right now. You can still see the mangled region on the top left under the chameleon head, with the 3 vertical lines that had appeared in pink on the display at the time. In it are previous fields from where the mouse was hovering before mixed with the present ones. It’s like the display isn’t flushing its memory properly.
I also noticed the bright pixels problem is most serious when browsing web pages with lots of animations and graphics in them. Anyway, reinstalled the G03 nvidia driver (319.17), problem still comes and goes 
Boot from a 12.3 Live image and see if the problem persists.
12.3 seems okay with flash and browser but I could not test the live system with the same visualization software I got installed in 12.1. Have to weigh carefully whether to install 12.3 or not. Got a lot of custom software to recompile.
The problem seems to be related to an incorrect colour depth somewhere. What I did is write an xorg.conf file with nvidia-xconfig just to make sure the correct colour depth (24) is hardwired. So far it seems to work.
