AFAIK this doesn’t work in VR mode because it’s an extra window. You won’t see it inside the glasses. The dev mode counter isn’t readable there either. (I used the windows counter, hit pause, took off the glasses and had a look 
I had a problem with the windows counter because the user didn’t belong to the correct group. But there is a workaround if you don’t get any numbers:
- run ‘cmd’ as admin, type this:
- net localgroup Leistungsprotokollbenutzer < Benutzername> /add
- reboot
Sorry, I have no idea what the original english word for 'Leistungsprotokollbenutzer" (german) is - ‘Benutzername’ equals ‘user name’
Pleas remove the space between ‘<’ and ‘Benutzername’ (that was the only way to write this sequence here)
