    Hey guys,

    Horizontal lines have started to pop up all over my display. It's been almost a week since it started. It began with Twitter and now the date/airport/battery options above the desktop have them in the drop down menu.

    I have attached an image of Twitter with the lines.

    Any help would be appreciated!

    Thanks.

    EDIT: I first uploaded a picture using Grab, which obviously wouldn't show the lines. The picture now is taken by my iPhone which shows the faults.

    Those lines are part of the GUI and no fault of any kind of hardware or software. Open the FILE or EDIT or :apple: menu to see the same lines. They are separators.

    Check the updated picture now. I know what separators are but I made a mistake using Grab to capture the image.
    Twitter should be white in the background of the tweets themselves and have black separators (like you said). My display shows horizontal lines everywhere which wasn't visible before.

    What exact MacBook Pro do you have (the one with the 8600M GT GPU perhaps, 2008 model)? And what Mac OS X version is on that MBP?
    Does the same happen in another, even temporarily created, user account?

    MacBook Pro (13-inch, Mid 2009)

    NVIDIA GeForce 9400M

    OS X 10.6.8

    And, yes, it does happen in other accounts!

    Will an upgrade to Mountain Lion fix it?

    I don't think so, I have almost the same model (17" MBP from 2009, but use the 9400M predominantly). It could be an hardware error, especially since it does not show up in a screenshot. Do you still have Apple Care or any other kind of warranty for that Mac?

    Nope, all expired.

    So is it terminal? Or will these line be the entire extent of the issue?

    That I don't know. It could be all there is, it could become more. You could contact Apple or an Apple Authorised Repair Centre and ask them, how much a diagnose would cost and if it is within your budget, you can find out more, what it actually is.

    I actually just figured out that the Mac only does this wherever there's any shading effect.

    Like with Twitter there's a gradient of off-white behind every tweet and underneath the MacRumors logo at the top of the page for example.

    According to Google, no one else seems to have this issue =/
