I've been using PCs since I can remember and Macintosh for about 6 years. I have a pretty decent idea of what's going on under the hood of computers. ...Or so I thought.
Shortly after I started using Macintosh computers, I've noticed rare and minor graphic glitches within application windows. The glitches occurred too quickly to get a good look, but once in a while it looked like a pixelated image of a frame of a video I had recently watched. Sometimes it looked like it was from a video I watched a week ago! But still, the little glitches happened too quickly to make anything of it, so I just dismissed it. I've never noticed this on PCs.
Just a few minutes ago, I was watching "All Good Things" by Nelly Furtado. I decided to install new updates, requiring me to restart my computer. When my computer finished loading, I opened a new tab in Safari—AND THERE IT WAS—Nelly's face all over Safari for ~3 seconds!
Why would the hardware retain a portions of a video I had watched from my previous session? Or more puzzling, possibly from even a week ago; where the computer had been completely shutdown for hours, clearing the RAM and VRAM for sure?
Does Apple use non-volatile RAM or something? Maybe that's why Apple RAM is so much more expensive lol
...This little graphics glitch happens on all my macs, all 3 of which have different brand GPUs (1 intel, 1 ATI and 1 NVIDIA).
