ive had my new mac mini with m4 pro for about a week now and it has worked fine but today i was playing World of warcraft and suddenly weird vertical lines (image 1) appeared on my screen. i shut down the game but i had some weird screen retention left (image 2). i restarted the mac but the retention was still there even after full restart but it has seemed to vanish after some time. i am using a hdmi 2.0 cable connected to my monitor running 2560x1440 at 144hz.

i do have a second monitor im using at the same time. i do not know how to test it now since the lines and retention have vanished and i do not know how to make the issue happen again in a timely manner

Oh, hm. It could either be a graphics issue or something up with the monitor

i had tg pro open and gpu temperatures were only 80 celcius

I would try the other monitor to see if it happens again, if it occurs again, it's a hardware issue with the Mac mini. If not, it could be a issue with the monitor.

And if it doesn't happen, take the Mac mini back to Apple and they should be able to either replace it or fix it (if possible)

#

It should be covered under the warrenty of the device

Also playing your game for long periods of time while running 144hz at 1440p could like… be a lot for the gpu
And 80 Celsius isn’t exactly cool, so it could be overheating

ill use the monitor wiht my windwos pc for a while to see if it happens. if not ill do what jared said and contact apple

if someone wanders to this post with the vertical line issue i managed to resolve the weird vertical lines by changing Color profile in Settings-Displays. if this is permanent fix remains to be seen or if it helps with the retention issue aswell.
