RC5: Flickering Screen With ATI Radeon 9700 and ViewSonic A90f+

I just installed FC3 -- RC5. The first time I logged into my account, I 
added a terminal window application launcher icon to my panel, and 
promptly opened the terminal window. A few minutes after doing this, an 
ugly pink flickering started up. the screen would flicker and the window 
would turn shades of pink from light to medium. Moving in and out of the 
terminal window (for example, switching focus to a Mozilla window) did 
not stop the flickering.

This is on an ATI Radeon 9700 card -- it's listed as an 9700 Pro 
although I think it might be an 9700 All In Wonder card -- with a 
ViewSonic A90f+ running at 1152 X 864 and 'millions of colors'.

I decided to 'shut down' the machine and turn it on again and see if 
that would help (that is, remove the flickering). This gave me a scare 
for a few moments because suddenly there was no output at all to my 
monitor! No BIOS messages...no Grub menu...just a steadily glowing 
'power' LED. I pressed the system 'reset' button once with the same 
effect. I tried it again after turning the monitor off and then on and 
that restored my video output! 

After a successful reboot, the flickering problem did go away. But while 
checking my display settings, I brought up Applications --> System 
Settings -->  Display and that restarted the flickering.
