I too have this exact same problem. It happened prior to the the 2004 update. I can't remember an exact version number I was using but since then I have tried graphics driver updates also.

Hi all,
A month or so ago I updated my windows 10 and noticed when I was focused on a window on one monitor it would bleed over onto the other monitor. I waited for the next windows 10 update to see if that would fix the issue, I updated my windows 10 version last week, but it did not fix my issue. Does anyone know how to stop the focused window from bleeding onto the second monitor?
I have posted a picture below that demonstrates the issue I am having.

2020-08-24T14:15:06+00:00 This started happening to me with full screen Teams after getting the Win 10 version 2004 update.
I'm not 100% sure which action actually resolved this for me but...
In my display settings I noticed my 2 external monitors were not set to the recommended resolution, so I changed them to the recommended resolution. I'm not 100% sure if the update changed my resolution, or changed the recommendation but the issue definitely began after the update.
I don't think that alone fixed it so then I went and moved the monitors around in the display settings UI, meaning I dragged monitor 2 from the left side of monitor 3 to the right side, applied the change, moved them to random positions and applied the change a couple times, then moved them back where I wanted them, applied the change again.
That seemed to fix the issue.
Hope that helps.

2020-09-16T19:32:17+00:00 This has been happening to me for over a year now -- I believe it's a bug in Windows.
I run my monitors at 125% so it might be related to DPI, using 1920x1200 resolution, 3 monitors side by side, with the center one being the primary. -- I've even reported this bug on the windows 10 bug reporter and it still happens.
It happens whether or not that Window is focused -- sometimes it takes awhile to happen -- usually just restoring and re-maximizing the window will fix the issue temporarily, but eventually it will happen again. It happens with any app on Windows, so it's definitely a windows bug.
Other thoughts: I'm really surprised by the MVP and Microsoft responses to this question -- like the pictures were very clear -- and it's obviously a bug -- like if you maximize a window on one screen it should STAY on that screen. -- It should not have one pixel on the side of that window float off onto another screen and show up on top of the windows on the other screens.
Microsoft, please fix this!!
