    I woke up my 15" 2012 Retina to what seemed to be a GPU glitch, a few hours after I had upgraded to Mavericks.

    Anyone else have this issue? I was not able to reproduce it after a restart.

    I saw something similar but only when my ram usage was high.
    It happened whilst rendering a screenshot I posted in another thread here.
    It also happened in the App Store window whilst I was downloading the Mavericks installer (for the second time) when the outsides of the App store window alternated from normally displayed to a series of thin stripes. The inside of the window remained fine.
    It hasn't happened since I've rebooted - yet.

    My rMBP is mid 2012
