XF270HU Fading Image burn?

When I came back to my desktop I noticed a distinct "after image" from a game. I could clearly see the residue of my health bar on my desktop.

Here are two screenshots: https://imgur.com/a/WjJh3nF

The image slowly fades away from view over the span of several minutes. Probably 10 minutes or so. If I turn off the screen it still persists. I've tried updating drivers on everything from the chipset, to the GPU, to the monitor in device manager. It still happens. I noticed that if I turn off G-Sync it does not have the same behavior. Is this a hardware issue or is this normal behavior?
I had a separate open ticket with the same question but we closed it a bit early. I was hoping to collect any other opinions/perspectives on the matter.
