Windows 10: Random screen unresponsiveness, cursor lags and no audio issue

Hello I am facing three different issues(not sure if related):

1) I recently started seeing these random freezes where screen becomes unresponsive to mouse clicks. But I am able to navigate via keyboard. No problem with the mouse itself. Happens with trackpad as well.

2) With my Nvidia shield controller plugged in, there is no audio from speakers when I open games and movies in vlc player. Also audio is not recorded( and not played as well) in camtasia studio, MSI afterburner. This issue started when I was messing with camtasia studio and spread to other apps.
This issue vanishes when I unplug the controller. Is the audio outputing to controller? If that's the case, the recorded video(while the controller plugged in) in camtasia should give sound when the controller is removed. But it doesn't. Does it mean, controller is trying to act like a microphone as well and not recording anything?

3) There are also minor cursor lags when opening or closing some applications.

Mouse pointer jumps and stutters after upgrade to 4k monitor.

I just watched the video you posted -- i don't think we had have the same problem. Your stuttering was constant whenever that mouse was used. Mine is more random -- like when if i close a window and move the mouse quickly somewhere the cursor will lag.

 

Mouse and Keyboard lagging and slow response since Windows 10 update

Almost a year later and I have the same lagging issue in Windows 10 and Outlook 2016 product. The problem is much more noticeable when multiple monitors are involved. Major lag problem moving the mouse between monitors. The lagging is also noticeable using
Microsoft Edge. Moving mouse/cursor to a monitor showing desktop is ok, but cursor lag is noticed as soon as Microsoft Edge or Outlook 2016 is on the same monitor. The lag is sometimes as much as 20 seconds at times. Very frustrating.
