When I am watching videos, online or on my hard drive, I get some screen distortion and I'm not sure what is causing it. Automatic graphics switching is turned off. Please help.
Here is an example of the distortion:
I have a 2010 Macbook Pro and am running OS X 10.9.2. My processor is a 2.4 GHz Intel Core i5 and I have 8 GB 1078 MHz DDR3 of RAM installed.
MacBook Pro, OS X Mavericks (10.9.2)
Please make a Genius Appointment and take it in for service.
Is that the Core i5 15" model? If so, your machine may be exhibiting some of the symptoms discussed here -> http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US.

I used Pehtis' suggestion here:

It has worked thus far.
Here is his post
"I think i have a possible solution to this problem, at least for the MacBook Pro 2010.
To fix it you have to disable compressed memory by typing the following command in the terminal:
sudo nvram boot-args="vm_compressor=1"
and then Restarting your Mac.
I'm guessing that its a bug in the driver of the Intel HD Graphics integrated GPU used in the 2010 MacBook Pro and somehow a part of the graphics RAM is accidentally compressed. I've been testing for a day or so and so far no graphics corruption at all.
If it gets fixed in an OSX update or it doesn't work for you you can use:
sudo nvram -d boot-args
and then Restart to reenable compressed memory.
It might affect other Intel GPUs so its worth a shot if you have a similar problem."
