Graphical glitches after installing mavericks

It looks like Apple's aware of the problem and is working on fixes related to "graphics drivers" in beta versions of 10.9.1...

I've been having issues with both the Mail app and these graphics glitches, so hopefully the next update will fix all of this.

Nice find. Thanks.

Same for me. Happens once in a while, reboot solves it.

Happened more with 4Gb memory, just repaired my logic board and with 8 GB it happens much less.

SOLUTION V2

The switching off of automatic graphics switching did not work for me, the problem was very persistant today no matter what I did

THEN I REMEMBERD, last week the problem started just as I was about to give a presentation to a university faculty, I had no time to play so I jacked in the Mini AVI VGA adapter for the projector and hoped the projection would work even if my screen was glitchy

restarted the laptop the and the problem went away and stayed away for the next 6 days as I gave four more lectures.

Today it started again (my problems seem worse than most examples I have seen here, my whole screen goes out sometimes with blue vertical lines).

TODAY I jacked in my Mini AVI VGA adapter (projector not atatched) and its fine again. I took it out for a few hours then when I hooked up my iPhone, iPhoto launched, mid importing some photos it happned again, had to force restart, jacked in the Mini AVI VGA adapter and its fine agaian.

so I have a work around.

looking forward to an OS patch

I am using:

MacBook Pro

17-inch, Early 2011

Processor 2.3 GHz Intel Core i7

Memory 8 GB 1333 MHz DDR3

Graphics AMD Radeon HD 6750M 1024 MB

Serial Number C02G40S5DRJN

Software OS X 10.9 (13A603)

just to report that my DVI - VGA fix is still working :-)

I think that this fix is likely doing the same thing as those who are using gfxCardStatus to change from the integrated to the discrete graphics card. It seems that for some reason toggling the graphics card in use helps to alleviate the issue.

I've been having the same issue as those have listed above. Seems to me that it must be a software bug and was hoping that Apple would have it fixed in 10.9.1 but I am still having the issues so it seems they didn't. Hopefully they are aware of it and working on pushing out a fix as it is a pretty annoying issue to have...

UPDATE - following the 10.9.1 update my display port - VGA fix stopped working. Went to the genius bar today, they were sure in thier own minds that it must be a GPU problem not OS, but after running hardware stress tests they could not find any fault. They replaced the motherboard anyway (yes this was all handled within a few hours), lets see what happens.

Thanks for the update. That is about what I would have expected them to say at the genius bar. I also agree that it seems like an OS issue and not a GPU problem. Looking forward to hearing how the new motherboard impacts the glitches.

P.S. when I restart there was a brief screen flash and large graphic aborations (big squares across the bottom of the screen) just as it was before the motherboard change.

and for the record : before the change of motherboard I had

Reinstalled OS 10.9

Restarted with command R repaired disk and repaird permissions - Results OK

Restarted with finger on D then performed hardware test. Results OK

Restarted with Shift alt command for a power managment reset

Restarted with alt command PR to reset the PRAM

Now I have a new motherboard and all seems OK except for those brief graphic aborations on startup,

Just chiming in to say that I'm also still getting the graphic glitches after installing the 10.9.1 update. I was really hoping that the update would resolve this, but no luck.

24 Hours since new motherboard installed (early 2011 macook pro 17") no issues other than the blink at startup.

I have a 2010 15" MacBook Pro running Mavericks and I also get graphics corruption from time to time especially after waking up from sleep.

I was also experiencing these issues on my mid-2010 iMac. Graphical glitches all over the place and my computer would hang. Constant restarts.

Then I realized that I had decided to switch back to using Safari as my main browser (since it got an update with Mavericks and I wanted to play with iCloud Keychain) and that necessitated installing Flash which I had never installed when I was using Chrome.

I remembered this because I started detecting a trend as to when the glitches would appear--whenever I went to a site in Safari that had some sort of Flash element. So I uninstalled Flash.

That was 3 days ago. Zero problems since.

...Oh, and I switched back to using Chrome. 😟 (But 🙂 at stuff working again.)

YMMV

I always used Safari, for me it was never related to what app I was running. I switched off Automatic graphics switching (System Prefrences > Energy Saver) and the glitches are gone. I think it has to do with the driver for Intel integrated graphics, as it is now always using nVidia GeForce GT 330M.

I have a similar problem with glitches when i reboot my Macbook Pro 13"( mid 2011) while its connected to my benq external monitor via 'mini display to hdmi'. The boot up hangs and I am left with no choice but to force shutdown the laptop. The MBP boots up with no issues as long as the HDMI cable is unplugged. Ive tried even booting up the above mentioned setup while the benq is powered down and the IEC power cable is unplugged, but to no avail. IMO, it is an issue with Mavericks that Apple has not bothered to address for a while, as there seem to be far to many similar complaints on these forums, since the release of osx 10.9. Any light on this issue would be much appreciated.
