Comment 5 for bug 782855

I have a theory that this may be related to heat. I almost never see bad fonts immediately after booting, but after a long session where the fan has been on a lot, the fonts will get worse and worse. If I suspend for a while, sometimes they get better, but I have seen corrupted fonts immediately upon resuming from suspend, so I'm not entirely convinced.

I should stress that this doesn't happen in Lucid, so even if it's heat releated, it's definitely caused by a software change.
