Hello Anahaym,
You can change this behavior by modifying the .RDP file for your connection.
the value is the setting "videoplaybackmode:i:1" to "videoplaybackmode:i:0".
(*in case the value doesn't exist, create it before the end)
You can read other suggestions and troubleshooting in a previous forums post here: https://social.technet.microsoft.com/Forums/windows/en-US/9fcf14e3-b831-443e-8d3b-7d7b6fbf6faf/remote-desktop-app-quotalways-on-topquot-after-fall-creators-update?forum=win10itprogeneral
Hope this helps with your query,
Best regards,
