    Hello guys,
    please I have this trouble from yesterday, I don't know what was happened, but I was worked as usually in Photoshop and this happened to me.
    At first few (2-3 seconds) some "ghost" shapes in type (black type goes 50/50 black and white) and after few seconds this mashup.

    I restarted my computer and all, but it does the same, in all documents in photoshop.
    Other apps are going good it seems.

    Please can you help me? I thing its some problem maybe with GPU?

    Thank you very much and have nice time,
    Petr Milk

    I am by no means a professional when it comes to these problems, but the first thing I do is reinstall OS X whenever I have had an issue with my Mac. Try that maybe? Is this with Adobe CC?

    Thank you, I try it later tonight, yes, all to factory settings,.. Its 2-3 year ago and I had similar troubleshooting with iMac early 2011, there was a bad GPU and they change in AppStore whole GPU + LCD (it was in apple care still, so no payment, because normal payment for this was circa 1.200 EUR, and it was terrible, because new complete was by circa 2.000E)

    Strange that nobody pointed it out yet, but it looks like GPU failure. GeForce GPU by any chance?
