Arch Linux

Shortly after starting a TigerVNC sesion, XVNC process continues to consume all available system memory, then swap and when all nsystem memory has been consumed, system halts.

This bug is applicable to XVNC as behavior is present with any vnc application which utilities XVNC backend

install tigervnc-1.12.0-3 and start vncserver session
execute "top" command to observe XVNC memory leak

Expected behavior
Previously memory would rarely exceed 0.5%

Client

OS: Arch Linux (vanilla)
VNC client: [e.g. Remmina & Apache Guacamole]
VNC client version: latest
Client downloaded from: Aur repo and docker

Server

OS: Arch Linux (vanilla)
VNC server: [have tried TigerVNC, TurboVNC & XRDP]
VNC server version: [latest]
Server downloaded from: [AUR/GIT]
Server was started using: [vncserver, etc]

If i restore my system to a backup taken 30 days prior issue is not present. Issue must therefore must be an package update.

Does not appear to be related to packages; Xorg, Mesa, Vulkan, Python, QT5, Intel, Nvidia

In an effort to troubleshoot, I upgraded these package independently and held back other updates and the issue was not present.
