On your hardware. I am also using F14 on my laptop (x86_64) with the
ATI driver, and I only see the problems you see under high system load,
which easily happens with thunderbird open (quite a few *large*
mailboxes) and a *lot* of tabs in 1 firefox window. Especially when
letting a FLASH window or two run for a couple of hours....
It is happening right
now, and here is the system load:
top - 10:07:19 up 1 day, 19:46, 4 users, load average: 0.28, 0.30, 0.16
It has been like this (i.e. the delayed workspace switch) as soon
as I loged in 1 day and 19 hours ago!!
Since I closed firefox (I now use Google chrome sparingly, and close
when I'm done), I'm running *much* better. My load avg hasn't shot up
yet (and it should have started doing so already based on my hightly
cron jobs!). I'll know more tomorrow morning after I suspend it an
Makes no difference here. Right now, I have no firefox running.
And thunderbird's cpu load is too small to be shown in the terminal
window in full screen mode (98x31 - I have to use large fonts).

I don't think they'll be interested unless you can prove its your xorg
But how can I prove it? Is there a way to instrument the
Xorg driver to leave a timing trail in a large circular buffer
for the workspace switch events? and then dump the buffer
to a file after N many events?
Just another thought, how long since you rebooted last? Sometimes
updates can require a reboot to work right. When was the last xorg
update you installed?
See above. Xorg got upgraded to fc14 about 1 day and
22 hours ago.
I suspect you have something mis-configured, but I have no clue as
what right now.
But I did not change any configuration between fc13 and fc14.
