Tracked down the original source on that image, here are both versions:
Unedited https://media.discordapp.net/attachments/271503305283338250/...
Watermark edges https://media.discordapp.net/attachments/271503305283338250/...
The grid of noise in the highlighted edges is from the jpeg compression on the screenshot, if we had the full quality original to work from it'd look cleaner.
