[Camino] "messed up pages"

[Bernd]

Before putting this one up on buqtrack, just a quick question. I sometimes,
maybe once in 5-6 months have an issue with Camino where all graphics mess
up on screen. I had this the day before yesterday with the current beta
while being on gmail. I tried to label a message and then all text becamme
blurry or rather pixels (in the drop down menu). I don't think this is a
problem with Camino but since Camino is my primary app on OS X this tends to
happen with Camino. The whole system then slows down, doesn't really
respond, only in short intervalls and top doesn't give any information on
what's going on. The messed up text then spreads over into other apps but
seems to affecct only menus and dialogs. But since the system slowly freezes
I can't take any screenshots or measure things. So I have no clue where this
comes from but maybe someone else has experienced this too and can tell me
where to fill in this bug.
I'm running 10.5.2 on a MBP 2,2 Santa Rosa.
