Occasional connection losses

I am noticing occasional connection losses recently (for a couple of months or so already; not before 1.16 for sure). The remote screen just freezes, and never comes back. Restarting the connection works well (I use shared connections on server side). I am not 100% sure, but it seems it happens during a high CPU load on server (when building some application for instance).

Steps to reproduce the behavior:

1. Connect to the most recent TigerVNC (git snapshot master branch) X11 vnc server (linux)
2. Have the remote connection opened for some time (can be days sometimes)
3. You shall suddenly find the remote screen frozen. Just waiting doesn't resolve it, you have to close the connection (client) and start a new connection (you find everything on the remote side went through in between, and is sunning smoothly all the time...); server restart is not needed

Expected behavior: Connection to remote TigerVNC server not to break (or, at least to recover)

Client:

• OS: Rocky Linux 9.8 (RHEL-9)
• VNC client: TigerVNC
• VNC client version: always the latest git snapshot - currently 1.16.80-0.5.git20260821.ff59f40
• Client downloaded from: custom build, RPM spec file based on RHEL / Fedora and TigerVNC provided one

Server:

• OS: Rocky Linux 9.8 (RHEL-9)
• VNC server:TigerVNC
• VNC server version: always the latest git snapshot - currently 1.16.80-0.5.git20260821.ff59f40
• Server downloaded from: custom build, RPM spec file based on RHEL / Fedora and TigerVNC provided one
• Server was started using: /usr/lib/systemd/system/[email protected] (ExecStart=-/usr/bin/Xvnc -inetd -query localhost -geometry 1024x768 -depth 24 -once -SecurityTypes=None)
