I rebuilt Firefox last night with Federico's patch and it does help. I then modified
the time in the patch for how long to store pixmaps before release from 5 seconds to .2
and built Firefox again. This made the problem almost disappear, of course real graphic
intense pages were dreadfully slow (but these sites are on the extreme side of things)
but the client and Firefox were both rock solid stable.
So I think a fix is on the horizon for Firefox which is hands down the largest offender.
But there are still other apps such as OpenOffice that will cause client instability.
That was the reason for heading to this list in search of a possible solution.
I did mess around with xorg.conf options such as XAANoOffscreenPixmaps,
XaaNoPixmapCache, an NoAccel in the device section. I was unable to get them to have
any effect but I also am not sure I am using them properly or if they should even have
any effect on my problem.
