UV islands that should not be there, but are seen after baking.

Hello. While the uv map is flawless, when I bake it in substance painter, the shapes appear. This is a new problem that I could not solve before. What is the solution? Where do these uv islands come from?
I use version 8.3.1

Also, this white stripe only appears on the ambient occlusion map.

Hello @leon_4546,

Thank you for the message and the screenshots.

From the shared image, I'd say there are two potential issues.

1. Make sure you High Poly mesh fit the low poly one.

2. Make sure you GPU is updated. It looks like this bug 

Best regards,

Thank you for your response. I found that the error disappeared when I updated my GPU driver. Thank you for your support.
