Windows 10: explorer windows merge/bleed into each other

Noted you work in an IT company.
Are you speaking of an effect you see on just one PC or a number of PCs configured similarly?

Please advise your Windows build
(Win key + R, winver)

Please go through the following basic steps.
1. Does this happen in Safe Mode?
If not, could be program conflict or a graphics driver issue.
If so, try a clean boot and check again.

2. If it does happen in Safe Mode, try creating a new user for test purposes.
Does it happen then?

3. If it happens in a new user account, that indicates you need to repair Windows.
Start with
From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Post back the result, which you can get after a restart as follows:
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!
Make sure the result is clear or fixed- else do not proceed.

Then at an admin prompt
SFC /SCANNOW
and report the result.

Thanks.

As for a screenshot, could you not erase all the text?
