Original GitHub issue: https://github.com/debauchee/barrier/issues/1248

Describe the bug
After gaming on the Windows 10 client for, say, twenty minutes or so, my Debian 10 server will freeze. I lose control of both keyboard and mouse, am unable to switch machine, and the only fix is a hard reset.

To Reproduce

It happens whenever I only use the client computer for more than a few minutes. Eventually, the server freezes.

Expected behavior
The ability to use the client computer without the server ever freezing or slowing down.

Screenshots
If applicable, add screenshots to help explain your problem.

Please do not link to image hosting sites, as these can be ephemeral. Instead, attach them to the issue.

Desktop (please complete the following information):

OS: Debian 10
Barrier version 2.3.3

Additional context

I've only been using Barrier for a day, and am new to the program.

After experimenting some more, I found that the server doesn't actually freeze. Rather, I lose control of my mouse and keyboard completely. Unplugging and replugging them doesn't work. The only way I can fix it is a hard reboot.

I have a similar issue and know how to reproduce.

Describe the bug
The Ubuntu machine running barrier server loses the mouse and keyboard. The machine is keep running, I can ssh into it and when I run showkey I can see the keyboard events, but the system just doesn't respond to the events. Restarting display-manager (systemctl restart display-manager) fixes everything.

To Reproduce
Run server 2.3.3 or 2.3.2 on Ubuntu and a client 2.3.2 on MacOS M1. On Ubuntu copy an image into the clipboard. The funny part is the image must be big enough, like 600x600. Start moving the cursor to the screen edge where the client is. And once the cursor jumps to the client, the server loses the mouse and keyboard, client disconnects.

Expected behavior
The server should gracefully handle the error without breaking the system.

Additional context
To work around this I had to disable clipboard sharing, which is a little inconvinient.

I have a similar situation where the client suddenly displays' dead 'after using it for a period of time. It turns out that I have turned on the keyboard's Scroll lock because my keyboard has 98 keys and there is no Scroll lock indicator light.
