Hey guys, I'm not sure if it was after the last patch but these days I notice that sometimes the bottom third of the display quickly flashes for like split of a second. First I thought it was safari issue as it was showing it there but then I noticed its actually in the whole screen. Anyone else has similar issue or experience? I just wonder if I need to take it to the apple store (which will be hard to demonstrate as it does it randomly and one can't really do certain thing to show it) or if there is something i could try at home. I've already done SMC reset but that didn't seem to help. Any similar experience or ideas, please?
