FWIW, I'm using two external 4k Dell monitors via usb-c, plus the laptop panel also at its max resolution (a bit lower then the monitors: 2880x1800 instead of 3840x2160), everything at 100% scaling.

But I have seen those "Atomic update failure" messages while at a sprint, where I only had my laptop and no external monitor. Back then, another symptom was the screen shifting a few pixels at random time, as if in an earthquake. I filed a kernel bug, and even found what looked like a patch we didn't have yet, but failed to pursue it as back home with the external monitor, that screen shifting problem didn't appear anymore. I"m trying to find that bug at the moment.
