So recently I came home after a few hours to my MacBook Pro (which was plugged in the whole day) and saw this:
What exactly would cause this?
More information on my system:
-
Hardware: 2.2 GHz Intel Core i7, 16 GB 2400 MHz DDR4, Intel UHD Graphics 630 1536 MB, Radeon Pro 555X
-
Software: I have Xcode installed, and the apps running in the background were Settings, Spotify, Atom (the text editor, with a fair number of plugins), and Chrome.
Update: Under Wilfred's suggestion, I ran a diagnostic. Nothing was picked up; it appears there are no issues according to it.

Yeah, that pattern looks like uninitialized video memory. That kind of thing happens when the machine comes out of sleep incorrectly or if there is a GPU memory pin that is coming loose. I say that because it’s a regular pattern.
Regardless, if it’s under warranty, be sure that Apple has noted that you reported a problem.
Better safe than sorry.
