Artifacting Occuring On MSI Optix G271 When Running at 144hz

[DriedSponge]

I'm having this strange issue with my monitor, where white lines will flicker across my screen when running at 144hz. When switching to 120hz, the artifacting disappears. I think the issue resides in my monitor because I've tried a different display port cables and a different ports on my graphics card, and the issue still persists. I have another monitor that is the exact same model (MSI Optix G271) and that uses the same model & brand of display port cable and it works perfectly fine. I don't think the monitor is physically damaged because I have never dropped it, hit it, battered it, etc. I got it last December and it has been sitting on my desk safely since then. Has anyone experienced an issue like this and may have some insight on possible solutions?

Thanks in advance.

Here is an image of the artifacting, it does not appear in screenshots so I took this photo with my phone:

It could be an internal issue with the monitor itself, that is not affected by the input signals coming into the monitor.

That is likely.

Damn that is quite unfortunate.

Yeah, time to RMA with MSI.

Similar problem with a similar outcome from a few years ago.

It seems to only occur once I turn on my PC. To fix it I switch to 120hz then back to 144hz. The artifacting usually doesn't return until I restart my PC again.
