Can someone do a quick test for me on Mavericks:

- Go into Recovery Mode (cmd+R when booting up)
- Select Get Help Online
- Does the Safari window search bar flicker or does the screen flicker anywhere else?
- Open the Yahoo tab, do you see any odd graphical artifacts? Try scrolling up and down and see if anything odd happens

If you do or do not see the issue: can you say what computer you are using and whether it has a dGPU?

Thanks! I'm trying to figure out if it's a software issue or a hardware issue
 
I responded to your other thread but I'm having the same issue as well on a late-'13 Macbook Pro with dGPU and Mavericks.
