There was an update to font rendering in gnome today, it may solve the problem. Besides, an advice would be to turn off font hinting in gdm. It triggers some payload on cpu and if you are fast scrolling on a f.ex. Pentium III class system, it may go "out of sync" with refreshing screen and crash X. Smoothing may be ok, hinting doesn't much improve overall look, but is taking up system resources.
