Not sure about this - I have built both Mozilla and Firefox with both O1 and O2, and get a problem. At seemingly random intervals, on no site in particular, when drawing a new page, I get rubbish on the screen - both inside the browser window and in other windows and on the root window - I have to shut down and restart X to have a usable system again. This only seems to happen when I use the browser, so I'm sure it's a Mozilla/Firefox problem. I haven't really had time to investigate and am new to Gentoo, so didn't really want to raise a bug without more investigation.
