After exiting a remote desktop session, cpu load goes up (dwm.exe) until next login

When I access another Windows 10 PC via remote desktop and then exit the remote desktop session, the CPU load goes up. It is DWM.EXE that causes it.

What I did to exclude other causes:

- scanned for viruses (yes, DWM.EXE is the original one from MS)

- made sure no magnifier was active (Google proposed this)

- made sure no screen saver is active and nothing else is on my lock screen

- made sure the gfx driver (Intel integrated) is up to date

dism /online /cleanup-image /checkhealth

dism /online /cleanup-image /scanhealth

sfc /scannow

chkdsk c: /f

do not show any problems.

Today I tried a second system as RDP target: Same problem! Could this be a bug? Can anyone else please try it, too? I don't know since when the problem occurs. Could be since 1903 (this is the version I use on both systems).

This is how it looks when I log the CPU loads:

Nothing happens if I hit Windows+F. Is there another way to submit feedback? An online form? I thought this support forums is monitored by developers, too.

I just copied the text into a feedback issue. I am using the German version, though...

Oh, and one more thing: Maybe I was not clear enough, but the problem occurs on the remote (target) system of the RDP connection (after the RDP connection is closed, but before any new logon).

I can no longer reproduce the error, I had to format it with release 1809, it was impossible to keep it like this. I had many other colleagues with this problem and they all rolled back. 

I recommend you go back with a system reset or by formatting if you can.
