[Ti] Strange screen 'jumps'

[John Griffin]

This happened when I installed Tiger on my Powerbook. The attached 17²
Studio Display started having the Œyips¹ like yours. I went into the ATI
System Preferences item (installed by the latest ATI software update) and it
reported that something had not been installed properly and it offered to
install it properly for me. I clicked OK, rebooted and everything has been
stable ever since.
