Apple Event: May 7th at 7 am PT
Since updating to macOS Catalina fullscreen video playback in the Music and TV app is plagued by frequent 0.5 second fadeouts to black (up to 7 per minute) which makes watching music videos or movies a pain in the rear. I would call this a serious regression. Please fix this ASAP. Thank you!

Hey there Dirk Lenz,
Thanks for reaching out to Apple Support Communities. I understand you’re not able to watch videos in fullscreen after updating to macOS Catalina. I’ll be happy to help.
If full screen isn’t working, reset the NVRAM and SMC on your Mac using the steps from these links:
How to reset the System Management Controller (SMC) on your Mac
Reset NVRAM or PRAM on your Mac
You may also want to see if this happens in safe mode or a new user account as well:
Use safe mode to isolate issues with your Mac
How to test an issue in another user account on your Mac
Also, see if this happens with all apps and videos.
Let me know if this helps.

Hey there A13_usr,
thank you for your help! Here is what happened:
Now here is where the Apple Magic happened ;-)
After logging back in with my regular user account it took quite some time for the first video to start after hitting Play. Since then the fadeout problem is completely gone.
While i have no idea what happened behind the scenes, the problem is solved and i am very happy.
Thanks again for your help A13_usr! Enjoy a happy and successful new year!
Dirk
EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...
Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.
This is one of several instances of just switching users cured the problem when returning to the original user.
I surmise some cache is cleared by switching users that isn't cleared byrestart or even a Safe Boot.
