I am connecting to macOS (Catalina 10.15.17) to remotely manage it. Connected from Ubuntu ( using Remmina & windows using tight VNC but same problem)

If I continue using mac remotely without switching between maximized windows of mac, it works fine, But as soon I try to switch between for example maximized window of mail app and safari app the screen always hangs and freezes without recovery, unless I reconnect vnc client Sharing a screen of when it hangs up, in the middle of switching two maximized screens while switching to other screen. Any help would be appreciated.

enter image description here

MORE INFORMATION The actual mouse pointer on the real machine (macOS) continues to move and clicks etc work, but on the client side image remains frozen as in screen shot.

  • Have you had a lot of apps opened while doing this?

  • @Thinkr No, not many apps.

  • I suggest you update your device and try again, you can make an edit of your question with the result.

  • VNC is a horrible tool. You’d be better off with something like TeamViewer. I long ago switched to CLI mode for nearly everything remote to my Mac,
