Computer hard crashes when alt tabbing

I have a late 2016(I think? it was the first MBP’s with touch bars) MBP and have never have any major issues until 8.1.5, or at least that’s when this issue seemed to first start occurring for me.

After my computer has been on for a couple of hours minimizing will lag my computer quite badly and eventually it just leads to a crash and I get this as the error report upon rebooting. Any help is appreciated.

Hey, Mäya!

This sounds like a possible overheating issue. The Panic itself is calling out IGGuC.cpp, which would be related to graphics driver firmware. You may want to reach out to Apple support to run a diagnostics and get some troubleshooting for possible overheating from them.

I would also recommend updating to the newest MacOS build: https://www.apple.com/macos/mojave/

This should update your graphics drivers.
