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)
