I've had this strange issue for the past few months now, where my MacBook will lock up completely, requiring a hold down of the power button to reboot the machine – but in addition to this the display, or external display which I am using most of the time, will be covered in green and pink lines (see below). The machine is totally unresponsive once this strikes, and seems to happen when streaming video – but maybe that's just because I've been doing a lot of that!
The model is a 2015 Retina 13" MacBook Pro, so it has integrated graphics only (Iris Graphics 6100), so it seems to be unrelated to most of the 15" MBP graphics issues I've heard about.
I've been to the Apple Store about this issue, but there was little they could do given that I am well out of warranty, but they could not find any hardware issues with whatever exact battery of tests they ran – and I could not replicate the issue as it is intermittent, happening maybe 1-2 times a week, but a few times it's happened several times on the same day.
Does anybody here have any familiarity with this issue, or just have any ideas on what might be causing it?
I am hoping it is not a complete logic board failure, and is instead either a software (unlikely?) or maybe overheating issue... as I've noticed the fan running loudly when the machine is in the frozen state, but I can't tell which one starts before the other.
The only thing I've had done to the machine lately is an official battery replacement 6 or so months ago as the original became swollen, so the machine had a "bottom shell replacement."

Thank you for whatever help you can offer.
