Original GitHub issue: https://github.com/debauchee/barrier/issues/1115

Describe the bug
I'm running latest version of Barrier Server (2.3.3) on my fresh-installed and patched Ubuntu 20.04.02 LTS.
When i use my Windows 10 laptop as a client, i'm experiencing lags during cursor movement/keyboard.
Cursor keeps freezing for some seconds right after "switch" event from Ubuntu to Windows.
After some seconds, freeze and lags seem to disappear and overall smoothness improve, but lags and freezes are still present over time.

To Reproduce

Steps to reproduce the behavior:

Start server in Ubuntu 20.04
Start client in Windows 10
Connect Windows to Ubuntu
Switch screen from Ubuntu to Windows

Expected behavior
No lags when moving cursor/writing on keyboard

Screenshots

Client Version:
-OS: Windows 10

Barrier version 2.3.3

Server Version:
-OS: Ubuntu 20.04.02 LTS

Barrier version 2.3.3

Are there any known lag problems when using Ubuntu as server and Windows as client?

I have an opposite issue with WIndows 10 server and Ubuntu client, sometime I can't move my mouse from Windows 10 to Ubuntu, it's blocked and I'm not sure what wrong.

Try hitting scroll lock. If so, this is a feature not a bug.
