I have yet to look up the specs to address whether the 16 GB of ram is enough to bridge the gap. I honestly was hoping to get a weigh-in on my hypothesis that this the result of an underpowered integrated GPU - or more importantly, validation that others have experienced the same thing (with or without it being an all-out failure). I didn't bother trying a third cable as the glitching has never appeared on the 4k monitor. I always use the thunderbolt/mini displayport to drive the monitor - and to date have used two different cables. My feeling is that if a bad cable was the cause, I'd see it no matter the circumstances.ģ. I question whether the built-in screen's display cable is the culprit as it doesn't happen when I am using it as my only monitor. Starting in safe mode seems to hamstring those same applications - so I can't really work in them.Ģ. It typically happens when I'm working in multiple GPU-intensive applications - not just when I have them all open. Doing so makes it difficult to mimic the same conditions that bring about the glitching in the first place.

I did try running the machine in Safe Mode briefly, but quickly realized it wasn't going to work. Well - I figured I'd see how many twists and turns the conversation tookġ.
