I upgraded to 10.6.8 from 10.6.3. The fonts for system are jagged, esp. the menus at the top of the screen, not matter what program is running. Other fonts seem to be a bit off too.

I did all the troubleshooting I know, including various maintenance and cleaning with onyx, removing fonts with font book, verifying fonts, resolving duplicates; removing non-system fonts; repairing permissions with both onyx and disk utility; holding down option on restart; deleting font cache and other caches; booting into safe mode; zapping the pram (haven't done that in many years.)

This happened before when I tried to upgrade. I went back to 10.6.3 because I couldn't figure it out.

The fonts look better when the display is set to 1440x900 but I can't read it that small. I always use 1152x70.

I'm stumped and grumpy.
