    Is anyone else getting graphical glitches, garbled images in Yosemite 10.10.1-10.10.2, with the GTX 980.

    It happens after a while of working with graphics apps and sometimes safari images in web pages are all garbled.

    I saw these issues on my macbook pro with 10.10 and 10.10.1, but are gone now in 10.10.2.

    Screenshots would be helpful. Good to know if it shows up in screen grab or if you have to take a photo.

    Can you describe it more in depth? I haven't seen any of the issue so far with mine.

    There was some glicthes with maxwell cards with 10.10-DPx drivers, but none I have seen since 10.10 came out. Check your vram for corruptions.

    Have a 970 and haven't seen any issues on 10.10.1 or 10.10.2 it's actually been running amazeballs.

    I have the exact same problem with a Titan X since 10.10.3. It happens only in Safari as the same files look fine in Preview.

    You can reset the VRAM by holding Cmd, Alt, P, R on startup, and continue to hold those keys down until you hear the Apple 'boot chime' 3 times. Then let go. It might be worth trying.

    EDIT: Sorry, as mentioned by another poster, that's for the NVRAM rather than the VRAM. Apologies for the confusion.

    That's for the PRAM, not VRAM. As far as I've experienced VRAM malfunction usually generates random and often flickering artifacts or color spots not restricted to images but on random places on the whole screen and/or KP.

    I'm not sure, but i think it comes with the Safari update. I don't notice the artefacts before.

    My bad, I was getting confused with NVRAM (another name for PRAM, I think on Intels rather than PPC) and VRAM.

    Sorry for the conflicting advice OP.

    I've had this problem happen on GTX680 and GTX780.

    Do you have the nVidia web drivers installed?

    Heh I'm using a GTX 980 on my 5,1 Mac Pro (MVC Flashed) and experiencing the same thing - I actually just sent them a message the other day. Never thought to isolate it to Safari.

    Are you guys using a UPS?
    I added a Cyberpower 1500V UPS and the problem seems to have gone away.

    "Expensive fix" but what can we do...

    Yes, also had this problem under 10.9 with GTX680 before a while. After an Update the problem was gone.

    Mmmmm, a solution, but why this works? At home i will change the two powercables of my GPU, perhaps it is a funny connection probleme.

    My dog barked and someone got off the elevator.

    Does that mean my dog made the person get off the elevator?

    Does that mean the person getting off the elevator made my dog bark?

    Or maybe the two things have nothing to do with each other.

    My vote is on number 3.
