Hi all, I updated to High Sierra on Friday and since then am having some fairly major issues with my display. There are two visible issues that are seemingly linked and hopefully you guys can help me out here please! When the brightness is turned down I get a "floodlight" sort of effect along the bottom of my display - I took a photo of the screen (attached) and you can see it at the bottom. Please excuse the smudgy fingerprint, I work in graphic design and people are always pointing at things! The second part of the issue is that when the brightness is not at max the brightness fluctuates a lot, more obviously when the brightness is all the way down, it's like it's sort of flickering. I called Apple and we have (excuse me if I get the terms wrong) - reset the SMC, reset the display RAM, booted into safe mode, ran diagnostics (came up with no errors) and we also wiped the hard drive and reinstalled the OS (High Sierra again). It possibly seems a little better after the wipe? Just wondering if this is a common issue with MBP and is just a coincidence that it happened at the same time as I upgraded? Or is it possible that there's a bug in the OS or something like that? The MacBook is a "Retina, 15-inch, Mid 2014" (bought in mid 2015), has 2.2GH i7, 16GB DDR3 memory, Intel Iris Pro 1536MB. Thanks very much for any help!
