I am on a 2015 13" MacBook Pro, and I have my setting so my computer never goes to actual sleep where the SSD is shutdown and all that, I just have my display set to turn off after 5 minutes. Anyway, when I wake my Mac up, right when the display turns on there is a quick what I would call "graphics glitch" where you see some crazy different colors (red, green, blue etc. but in no order, scattered all over the place) and then bam it goes away and my desktop is showing and the screen is perfect. There is no issue with the screen after that one second or less (probably less) glitch and everything looks great. I am assuming it is just a glitch in High Sierra that will probably be patched in the next release. Anyone else experience anything like this, and if so or not, is it something I should worry about or would you think like I do it is just a High Sierra glitch that will be patched? I really do not want to have to do another clean install. Thanks in advance! EDIT: I was reading through the "High Sierra bugs and bug fixes" thread and saw at least four other people with the same exact issue on the same exact MBP, one even had a screenshot. Must be an issue with our GPU, which is Intel Iris 6100. At least now I can rest easy knowing my machine is not going bad!
