[QUOTE="andyhume, post: 379011, member: 30381"] Hi, Ever since a security update to Tiger 2 days ago (not sure if it's related to this but it first occured on boot up afterwards) my Powerbook G4 screen has had a weird screen alignment issue that is quite hard to describe. The best way I can find to describe it is if you mentally imagine the screen being split into quarters, when you move the mouse cursor from one to the other a strip of the screen image moves by one pixel. If you move the mouse from top half to bottom half the flicker is on a horixontal axis, and if you move the mouse from left to right it is on the vertical axis. Does this make sense to anyone, and is there anything I can do to fix it? Does it sound like a hardware problem? Thanks, andy. [/QUOTE]
