Steps to reproduce the problem:
I'm trying to use Chrome Remote Desktop for the first time. When connected, host with running Chrome Remote Desktop 'server' has process dwm.exe consuming ~25% CPU (runs under some internal user DWM-2). According to ProcessExplorer (from Windows Internals) there are 2 (of 9 total) thread consuming CPU - it shows following stack traces for them

When connecting to that same host using native Windows Remote Desktop - dwm.exe consumes 0% CPU, and in that case there are 2 instances of dwm.exe process - both eating 0%. 

What is the expected behavior?
dwm.exe and other supplementary staff should consume close-to-zero CPU.

What went wrong?
dwm.exe uses 25% CPU + other Remote Desktop processes eat roughly 5-10% with total of 30-35%. 

Note: host intentionally has rather slow (and low power CPU) CPU - Celeron 1037U. It may happen that CPU usage on more powerful CPUs will be significantly lower.
