During the past 3 days I have experienced the following issue: when returning from sleep, I see an extremely garbled version of my desktop. The only thing that seems to help is a reboot.
My first guess is that this is related to the video card. After looking into this issue, I found a lot of problems related to ML and returning from sleep, such as this post on AskDifferent: How to stop MacBook Pro (Retina) from freezing/locking at the login/authentication dialogue, after wake? but I think this is a different issue because it does not speak of a garbled screen.
Some more details:
- System: MacBook Pro 15" early 2011, 2,2GHZ I7, 8GB Ram, AMD Radeon HD6750M 1024
- The issue seems to happen only when I open my laptop in the morning; if I close and open my laptop during the day, it does not seem to happen.
- The issue 'solves' when rebooting.
