Has anyone seen this before? I have a new Macbook Pro Retina (Mid 2015). Only 6 months old. I am super careful with it. I barely have anything installed on it (Adobe CC, Microsoft Office, Steam with about three games -- that's about it) but I'm getting the following glitches very frequently: It seems to happen when I watch an online video in YouTube or something. I use Chrome as my browser. What's especially interesting is that I took a screenshot while the glitches were happening... and they appeared in the .png -- which seems to show it's a software issue, not hardware. This really surprised me. Apple support have not been very helpful so far. I've had two online chats. The first one told me to reset the SMC and PRAM -- which I did, to not avail. I've sent the above videos to them and now they've asked me to keep monitoring it in different browsers to see if I can identify what's causing it for them. Not very helpful! There's clearly a major fault and it's still under warranty. Has anyone seen this before?
