I was working in Photoshop and all of a sudden my screen froze and was full of horizontal lines. Tried multiple restarts, finally had apple get it back to normal, only for it to happen all over again when I went back into Photoshop. I took pictures but don't know how to post them here. Has anyone seen this or know what could be going on?? Only happens in photoshop.
Sounds like a bad video card driver, or a bad video card.
That's what AppleCare said too. It seems to happen as soon as I zoom in and use a brush. Made an appointment with the Apple Store tomorrow so hopefully if it is the card they can fix it.
What model of Macintosh do you have?
What OS version are you using?
Was the display mess up outside the Photoshop windows, or just in the Photoshop document window?
