I have an updated picture, because it seems my issue wasn't reproduceable.

On the right is the Brave browser window and on the left is Google Chrome, just so you know ( on the left could have been any window, I just happened to have Chrome opened).
You can clearly see the black border.

I was going to submit this same issue, but when I searched, I found this. It happens on my computer with the same setup.

We captured (and fixed) the same issue with #6258

The issue you link to @Superbest is related, but is different. I'm curious if it's fixed too
