M1 MacBook Users Say Their Screens Are Cracking for “No Apparent Reason”

I'm also having a weird issue related to the screen on a M1 Macbook Pro. Every other month, the screen randomly turns blank. The backlight still works, and every time the laptop opens it flickers for a couple of seconds with a bit of the image visible, so it seems that the screen itself is still working.

After a few days, it randomly works again after a reboot. But never immediately. I suspect something with the GPU, as a Shadertoy visit once triggered it.

The issue is irreparable. Once it gets into repair, and I've lost my laptop for a few weeks, it will randomly work again after a few days and they'll say there's nothing wrong.

I haven't stress tested an M1 yet, but you can try this. With nothing else running. Load up the CPU with YES outputting to /dev/null. This should bring CPU usage to 100%. Then open several games of chess, make it CPU vs CPU and make them full screen. See if you experience the same issue.

$yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null &

Is /dev/zero to bypass the FS?

It spikes up the CPU like crazy.
