Active user sometimes shows blank when PC is in use #4044

Hey there,

I've occasionally seen where MeshCentral's console reports no active user on a PC, but when I remote control, I find a user is logged in and active on the PC.

Neighboring PC shows active user: image

If I was to remote control that first screenshot PC, I will see the user is definitely logged in and active. I can also see via the CLI tool 'qwinsta' that a console session is active:

This isn't a major issue but wondered if it had been seen or reported before and any ideas on what the issue is? I think restarting MeshCentral server or the agent fixes it, but I haven't been able to easily reproduce it to pinpoint what resolves it.

Thanks!

I have observed this when a user is connected to the server via RDP. At the moment when the user's RDP connection window is minimized, I cannot connect to his session. When the window is expanded, then I can connect to its session on the server.

I noticed that a while ago. When the rdp session is minimized, the OS does not allow screen capture. I think it's a limitation/optimization on how windows renders rdp sessions.

When the rdp session is minimized the screen capture process terminates, and when I try to respawn it, I get a security exception.

In my instance, the PC is a Windows 10 desktop and the user is logged in via console.
