Hi there! A few days ago, I started noticing that when my 15" Macbook Pro's display goes to sleep, a weird artifact appears on the also turned-off Touch Bar, right besides the Touch ID button. Sometimes it just stays there fixed, and sometimes it flickers. As soon as I wake up the display or touch any key, the regular buttons appear on the Touch Bar and the artifact goes away. Does anybody know what this might be, or perhaps someone has this issue too? Any thoughts besides bringing the computer to Apple? I'm traveling at the moment, so that's not a option. I've already reset both the SMC and the NVRAM to no avail. This issue does not presents itself during the first hour of usage, as if it was usage/heat/apps/whatever dependent. Thanks in advance for any help!
